Anticoagulants: A Perspective of Medical Devices Inventor: Carl Goosen

Author: Carl Goosen

 

Anticoagulants are the reason the bulk of prosthetic heart valves are no longer acceptable, and the catheter delivery has taken over. I am amazed how this miracle has taken over, since even the 24 hour survival rate should not be tolerated, apart from longer term might not be acceptable. The problem with all the popular valves is caused by two factors, viz., turbulence and shear forces.

Turbulence takes place while cusp mechanisms act in the highest flow area, This is present in ALL the “normal” prosthetic valves, EXCEPT MINE. My poppet moves above the seat into a slower flow area where turbulence causes “happy” vortices, which are present in normal hearts. Ajit Yoganathan, considered to be the”guru” of all the studies in this matter suggests that the areas below and above the high speed flow section are safe from damage for 5 mm and on. When my valves are open their poppets are in the safe zone and the aortic poppet’s streamline assures no disturbance. Turbulence causes defribination causes clotting which may cause emboli.

The hinge mechanisms that are used in most “regular” valves must allow free movement so the small clearance leads to shear forces, possibly hemolysing some blood.

Although there is no need for anticoagulants inmy prostheses, the FDA mandate does not permit not using anticoagulants. Even if they allowed it the doctors would take as long as when they would not give up phlebotomy. ( They still practice it in the Middle East)

By the way, there is no validity in the concept of accelerated time studies. It is not possible to divorce force from speed. A tenfold increase in speed equals an eighty-fold increase in force,

Before the FDA mandated the use of anticoagulants we had a series of patients with my aortic valve without anticoagulants. The longest one was for 13 years and he became the president of a corporation.After I left Cape Town the cardiologist fooled around with the concept and induced embolism which did not occur in the patients not on anticoagulants

ONE Critical Medical Device: Aortic Valve Prosthesis — The Inventor Perspective on Design

Author: Carl Goosen, Goosen Enterprises, LLC, CEO

 

The Aortic Prosthesis

For 18 months after he started using my mitral valve, Christiaan Barnard demanded an aortic prosthesis.”Everybody uses the same valve and just changes the sewing ring” My reply: That is not the way to go.Just look at the natural valves, they have opposite functions. The aortic has high pressure and high velocity, the mitral low pressure and velocity” When I try to solve a problem, I have found it is better to leave it on the “corner of my mind “ and the answer will hit me suddenly.

 

In our day it was normal to have only one car. My wife needed it and I decided to walk the mile and a half to work. As I walked up the hill to the hospital with the winter sun beating on my neck, it hit me. It was a Thursday and we did not have a case. I stood still and sketched my idea on the back of a cigarette carton. I have lost the souvenir long since. On Sunday evening I was sewing the cushion on a complete new aortic prosthesis.

 

Barnard had an engineer brother attached to the Salt River Railway workshops capable of the most sophisticated engineering. They built complete steam locomotives. I believe they had a staff of about a thousand. He was in charge of a program trying to prevent smokestacks from starting fires in the countryside. He had connection with the Minister of Railways who gave them permission to make the valve ostensibly as an emergency life saving device. I sat for 3 hours with engineers and draftsmen turning my design into reality. Finally I passed the drawings and gave over control to 15 top tool and die makers and 5 machinists. They worked round the clock in 8-hour shifts while I cat-napped in an office. The molds for the silicone poppets and the manufacture of the stainless steel frames were ready by 4pm Sunday. By evening I had the poppets ready and vulcanized. I sewed on the sewing cushions and assembled the first units (3 sizes). Surgery was done Monday at 8 am.This is the original design which was used for many years. We have discovered patients who had long term survival with no problems. ( Both had been anticoagulated unnecessarily) in whom the valve had functioned perfectly. One in Bloemfontein South Africa had the valve explanted in error since a new (other) valve did not relieve her rheumatic heart ( the reason for her original valve implant) The valve had functioned well for 34 years. I have this valve in my possession and believe it can outlive any patient.

The other long term was found in Athens, Greece. She had her valve for 37 years when first reported. Her valve was shown to be functioning perfectly. She had surgery scheduled for mitral stenosis at the 38 year mark but succumbed to a botched intubation. We were not able to receive the specimen. ( Enclosed X-rays show perfect function of my valve) Both these patients had my valve inserted by Christiaan Barnard at the Groote Schuur Hospital, Cape Town, South Africa in 1970.

 

It is time to discuss the reason for my aortic valve design. Everything begins with the Starr-Edwards ball-in-cage design. The primary lesion is aortic stenosis. The maximum orifice that can be squeezed out of the space is the question. Early models of the S-E had problems where the ball got stuck with fatal results. I thought of enlarging the orifice and having projections into it to stop the ball from sticking but under constant pressure to get somewhere, abandoned it. Enlarging the ball diameter and using a segment of a sphere seemed a good idea. Since the required flow is about 80 cc in about three-tenths of a second a streamlined poppet becomes essential. I achieved this by mounting a cone on a segment of a sphere. To control the poppet it has two poles. These are held in place by two small rings held by arms above and below. These guide poles assist in the streamline by steering the flow during systole and pulling it together in the ventricle. I also liked the streamline to feed the coronary flow entry during diastole.

This is a very brief summary which should be exposed to qualified engineers .

Capillaries: A Mapping Geometrical Method using Organ 3D Printing

Reporter: Aviva Lev-Ari, PhD, RN

Major 3D Printed Organ Breakthrough: Vascular Networks Achieved

Bio-printing promises to change the way the medical community deals with organ failure. Every year hundreds of thousands of people die because they could not receive an organ transplant soon enough. The demand for organs-1donor organs far exceeds the supply, leaving helpless patients in a state that no one should have to be left in… waiting to live.

We have already seen 3D printing create several types of human tissue, most notably liver tissue which is currently being used in drug toxicity testing. With that said, there is still one major hurdle to get us from the tiny sheets of 3D printed organ tissue, to that of entire 3D printed organs, which could one day be created by a patient’s own stem cells, and transplanted to save their life. That hurdle is the vascularisation of those organs. Every cell within a human organ, such as the liver, kidney or heart are within a hair’s width of a blood supply.  This is an incredibly complex setup, one which up until now, researchers have found to be a nightmare to overcome when dealing with bioprinting. Without an adequate vascular network, the cells would be starved of oxygen, as well as a means to excrete waste, causing them to die and making the printed organs worthless.

Scientists from the Universities of Sydney, Harvard, Stanford and MIT have been working together to overcome these mountainous hurdles. Today, the University of Sydney made a groundbreaking announcement. The team of scientists from all four universities have figured out a technique, making such vascularisation possible within the 3D bioprinting process.

Vascular Network of the Human Liver

To achieve this, the researchers used an extremely advanced bioprinter to fabricate tiny fibers, all interconnected, which would represent the complex vascular structure of an organ. They coated the fibers with human organs-3endothelial cells, and then covered it with a protein based material, rich in cells. The cell infused material was then hardened with the application of light. Once hardened the researchers carefully removed the coated fibers, leaving behind an intricate network of tiny spaces throughout the hardened cell material. The human endothelial cells were left behind, along the tiny spaces created by the fibers, which after a week self organized into stable capillaries.

“While recreating little parts of tissues in the lab is something that we have already been able to do, the possibility of printing three-dimensional tissues with functional blood capillaries in the blink of an eye is a game changer,” said study lead author and University of Sydney researcher, Dr Luiz Bertassoni. “Of course, simplified regenerative materials have long been available, but true regeneration of complex and functional organs is what doctors really want and patients really need, and this is the objective of our work.”

The discovery of this technique should hopefully quicken the pace of bio-printing research, and lead to a time, in the not too distant future, when we can meet the demand of the growing need for organs transplants. We are still likely several years from such a time, but progress is certainly being made quite rapidly.

A step closer to bio-printing transplantable tissues and organs


2 July 2014

 

Researchers have made a giant leap towards the goal of ‘bio-printing’ transplantable tissues and organs for people affected by major diseases and trauma injuries, a new study reports.

 

Scientists from the Universities of Sydney, Harvard, Stanford and MIT have bio-printed artificial vascular networks mimicking the body’s circulatory system that are necessary for growing large complex tissues.

 

“Thousands of people die each year due to a lack of organs for transplantation,” says study lead author and University of Sydney researcher, Dr Luiz Bertassoni.

 

“Many more are subjected to the surgical removal of tissues and organs due to cancer, or they’re involved in accidents with large fractures and injuries.

 

“Imagine being able to walk into a hospital and have a full organ printed – or bio-printed, as we call it – with all the cells, proteins and blood vessels in the right place, simply by pushing the ‘print’ button in your computer screen.

 

“We are still far away from that, but our research is addressing exactly that. Our finding is an important new step towards achieving these goals.

 

“At the moment, we are pretty much printing ‘prototypes’ that, as we improve, will eventually be used to change the way we treat patients worldwide.”

 

The research challenge – networking cells with a blood supply

 

Cells need ready access to nutrients, oxygen and an effective ‘waste disposal’ system to sustain life. This is why ‘vascularisation’ – a functional transportation system – is central to the engineering of biological tissues and organs.

 

“One of the greatest challenges to the engineering of large tissues and organs is growing a network of blood vessels and capillaries,” says Dr Bertassoni.

 

“Cells die without an adequate blood supply because blood supplies oxygen that’s necessary for cells to grow and perform a range of functions in the body.”

 

“To illustrate the scale and complexity of the bio-engineering challenge we face, consider that every cell in the body is just a hair’s width from a supply of oxygenated blood.

 

“Replicating the complexity of these networks has been a stumbling block preventing tissue engineering from becoming a real world clinical application.”

 

But this is what researchers have now achieved.

 

What the researchers achieved

 

Using a high-tech ‘bio-printer’, the researchers fabricated a multitude of interconnected tiny fibres to serve as the mold for the artificial blood vessels.

 

They then covered the 3D printed structure with a cell-rich protein-based material, which was solidified by applying light to it. Lastly they removed the bio-printed fibres to leave behind a network of tiny channels coated with human endothelial cells, which self organised to form stable blood capillaries in less than a week.

 

The study reveals that the bioprinted vascular networks promoted significantly better cell survival, differentiation and proliferation compared to cells that received no nutrient supply.

 

Significance of the breakthrough

 

According to Dr Bertassoni, a major benefit of the new bio-printing technique is the ability to fabricate large three-dimensional micro-vascular channels capable of supporting life on the fly, with enough precision to match individual patients’ needs.

 

“While recreating little parts of tissues in the lab is something that we have already been able to do, the possibility of printing three-dimensional tissues with functional blood capillaries in the blink of an eye is a game changer,” he says.

 

“Of course, simplified regenerative materials have long been available, but true regeneration of complex and functional organs is what doctors really want and patients really need, and this is the objective of our work.

 

Watch bio-printing in action here.

Soft Tissue Transponder for Radiotherapy and Radiosurgery Treatments for Cancer got FDA Approval

Reporter: Aviva Lev-Ari, PhD, RN

Varian Medical Systems ($VAR) scored FDA 510(k) clearance for its soft tissue transponder for radiotherapy and radiosurgery treatments

 

FDA clears Varian soft tissue transponder to treat cancer

Varian Medical Systems’ Calypso soft tissue Beacon transponder–Courtesy of Varian

Varian Medical Systems ($VAR) scored FDA 510(k) clearance for its soft tissue transponder for radiotherapy and radiosurgery treatments.

The Palo Alto, CA-based company’s Calypso soft tissue Beacon transponders are implanted in soft tissue throughout the body, allowing physicians to target high energy treatment beam radiation at tumors without damaging surrounding tissue. The grain-sized device includes a real-time GPS monitoring system that continuously tracks and monitors the position of transponders during radiosurgery.

An earlier version of the product was cleared for use in the prostate and prostatic bed, but the new indication expands the device’s applications for other types of cancer, the company said in a statement. Varian plans to release the transponders toward the end of this year, and expects a full commercial roll-out in 2015.

“We’re pleased to be able to make the system available to clinicians who want to use it more broadly, not just for conventional radiotherapy but for some of the newer approaches, like stereotactic body radiotherapy (SBRT), which involves delivering higher radiation doses very quickly,” Andrea Morgan, Calypso product manager said in a statement. “For treatments like that, accurate targeting is essential, and the new Calypso transponders have an important role to play.”

The FDA nod bodes well for Varian, as the company struggles to recover from a disappointing second quarter. The devicemaker saw its net earnings fall nearly 18% in Q2, with profits of $92.7 million down from $112.8 million the same period last year. Revenue increased 1% to $779 million, primarily due to a 4% jump in oncology sales and a slight uptick in imaging components.

Regulatory blessings also help Varian forge ahead in its emerging markets, where the company sees strong demand for its oncology and medical imaging products. Last year, Varian built its first Asian subsidiary in South Korea, giving it an expanded market for its cancer-treating radiotherapy devices and imaging equipment. In January, the company renewed a three-year, $515 billion deal withToshiba Medical Systems to supply medical imaging components. The companies originally charted the deal in January 2011 for an estimated $450 billion.

Varian Medical Systems

Varian Medical Systems, Inc., of Palo Alto, California, is the world’s leading manufacturer of medical devices and software for treating cancer and other medical conditions with radiotherapy, radiosurgery, and brachytherapy. The company supplies informatics software for managing comprehensive cancer clinics, radiotherapy centers and medical oncology practices. Varian is a premier supplier of tubes, digital detectors, and image processing workstations for X-ray imaging in medical, scientific, and industrial applications and also supplies high-energy X-ray devices for cargo screening and non-destructive testing applications.  Varian Medical Systems employs approximately 6500 people who are located at manufacturing sites in North America, Europe, and China and approximately 70 sales and support offices around the world.

Why did this occur? The matter of Individual Actions Undermining Trust, The Patent Dilemma and The Value of a Clinical Trials

Why did this occur? The matter of Individual Actions Undermining Trust, The Patent Dilemma and The Value of a Clinical Trials

Reporter and Curator: Larry H. Bernstein, MD, FCAP

 

he large amount of funding tied to continued research and support of postdoctoral fellows leads one to ask how following the money can lead to discredited work in th elite scientific community.

Moreover, the pressure to publish in prestigious journals with high impact factors is a road to academic promotion.  In the last twenty years, it is unusual to find submissions for review with less than 6-8 authors, with the statement that all contributed to the work.  These factors can’t be discounted outright, but it is easy for work to fall through the cracks when a key investigator has over 200 publications and holds tenure in a great research environment.  But that is where we find ourselves today.

There is another issue that comes up, which is also related to the issue of carrying out research, and then protecting the work for commercialization.  It is more complicated in the sense that it is necessary to determine whether there is prior art, and then there is the possibility that after the cost of filing patent and a 6 year delay in obtaining protection, there is as great a cost in bringing the patent to finasl production.

I.  Individual actions undermining trust.

II. The patent dilemma.

III. The value of a clinical trial.

Science 18 July 2014: Vol. 345 no. 6194 p. 254 DOI: 10.1126/science.345.6194.25

 

In the study of cardiac regeneration, Piero Anversa is among the heavy hitters. His research into the heart’s repair mechanisms helped kick-start the field of cardiac cell therapy (see main story). After more than 4 decades of research and 350 papers, he heads a lab at Harvard Medical School’s Brigham and Women’s Hospital (BWH) in Boston that has more than $6 million in active grant funding from the National Institutes of Health (NIH). He is also an outspoken voice in a field full of disagreement.

So when an ongoing BWH investigation of the lab came to light earlier this year, Anversa’s colleagues were transfixed. “Reactions in the field run the gamut from disbelief to vindication,” says Mark Sussman, a cardiovascular researcher at San Diego State University in California who has collaborated with Anversa. By Sussman’s account, Anversa’s reputation for “pushing the envelope” and “challenging existing dogma” has generated some criticism. Others, however, say that the disputes run deeper—to doubts about a cell therapy his lab has developed and about the group’s scientific integrity. Anversa told Science he was unable to comment during the investigation.

“People are talking about this all the time—at every scientific meeting I go to,” says Charles Murry, a cardiovascular pathologist at the University of Washington, Seattle. “It’s of grave concern to people in the field, but it’s been frustrating,” because no information is available about BWH’s investigation. BWH would not comment for this article, other than to say that it addresses concerns about its researchers confidentially.

In April, however, the journal Circulation agreed to Harvard’s request to retract a 2012 paper on which Anversa is a corresponding author, citing “compromised” data. The Lancet also issued an “Expression of Concern” about a 2011 paper reporting results from a clinical trial, known as SCIPIO, on which Anversa collaborated. According to a notice from the journal, two supplemental figures are at issue.

For some, Anversa’s status has earned him the benefit of the doubt. “Obviously, this is very disconcerting,” says Timothy Kamp, a cardiologist at the University of Wisconsin, Madison, but “I would be surprised if it was an implication of a whole career of research.”

Throughout that career, Anversa has argued that the heart is a prolific, lifelong factory for new muscle cells. Most now accept the view that the adult heart can regenerate muscle, but many have sparred with Anversa over his high estimates for the rate of this turnover, which he maintained in the retracted Circulation paper.

Anversa’s group also pioneered a method of separating cells with potential regenerative abilities from other cardiac tissue based on the presence of a protein called c-kit. After publishing evidence that these cardiac c-kit+cells spur new muscle growth in rodent hearts, the group collaborated in the SCIPIO trial to inject them into patients with heart failure. In The Lancet, the scientists reported that the therapy was safe and showed modest ability to strengthen the heart—evidence that many found intriguing and provocative. Roberto Bolli, the cardiologist whose group at the University of Louisville in Kentucky ran the SCIPIO trial, plans to test c-kit+ cells in further clinical trials as part of the NIH-funded Cardiovascular Cell Therapy Research Network.

But others have been unable to reproduce the dramatic effects Anversa saw in animals, and some have questioned whether these cells really have stem cell–like properties. In May, a group led by Jeffery Molkentin, a molecular biologist at Cincinnati Children’s Hospital Medical Center in Ohio, published a paper in Nature tracing the genetic lineage of c-kit+ cells that reside in the heart. He concluded that although they did make new muscle cells, the number is “astonishingly low” and likely not enough to contribute to the repair of damaged hearts. Still, Molkentin says that he “believe[s] in their therapeutic potential” and that he and Anversa have discussed collaborating.

Now, an anonymous blogger claims that problems in the Anversa lab go beyond controversial findings. In a letter published on the blog Retraction Watch on 30 May, a former research fellow in the Anversa lab described a lab culture focused on protecting the c-kit+ cell hypothesis: “[A]ll data that did not point to the ‘truth’ of the hypothesis were considered wrong,” the person wrote. But another former lab member offers a different perspective. “I had a great experience,” says Federica Limana, a cardiovascular disease researcher at IRCCS San Raffaele Pisana in Rome who spent 2 years of her Ph.D. work with the group in 1999 and 2000, as it was beginning to investigate c-kit+ cells. “In that period, there was no such pressure” to produce any particular result, she says.

Accusations about the lab’s integrity, combined with continued silence from BWH, are deeply troubling for scientists who have staked their research on theories that Anversa helped pioneer. Some have criticized BWH for requesting retractions in the midst of an investigation. “Scientific reputations and careers hang in the balance,” Sussman says, “so everyone should wait until all facts are clearly and fully disclosed.”

 

II.  Trolling Along: Recent Commotion About Patent Trolls

July 17, 2014

PriceWaterhouseCoopers recently released a study about 2014 Patent Litigation. PwC’s ultimate conclusion was that case volume increased vastly and damages continue a general decline, but what’s making headlines everywhere is that “patent trolls” now account for 67% of all new patent lawsuits (see, e.g., Washington Post and Fast Company).

Surprisingly, looking at PwC’s study, the word “troll” is not to be found. So, with regard to patent trolls, what does this study really mean for companies, patent owners and casual onlookers?

First of all, who are these trolls?

“Patent Troll” is a label applied to patent owners who do not make or manufacture a product, or offer a service. Patent trolls live (and die) by suing others for allegedly practicing an invention that is claimed by their patents.

The politically correct term is Non-practicing Entity (NPE). PwC solely uses the term NPE, which it defines as an entity that does not have the capability to design, manufacture, or distribute products with features protected by the patent.

So, what’s so bad about them?

The common impression of an NPEs is a business venture looking to collect and monetize assets (i.e., patents). In the most basic strategy, an NPE typically buys patents with broad claims that cover a wide variety of technologies and markets, and then sues a large group of alleged patent infringers in the hope to collect a licensing royalty or a settlement. NPEs typically don’t want to spend money on a trial unless they have to, and one tactic uses settlements with smaller businesses to build a “war chest” for potential suits with larger companies.

NPEs initiating a lawsuit can be viewed positively, such as a just defense of the lowly inventor who sold his patent to someone (with deeper pockets) who could fund the litigation to protect the inventor’s hard work against a mega-conglomerate who ripped off his idea.

Or NPE litigation can be seen negatively, such as an attorney’s demand letter on behalf of an anonymous shell corporation to shake down dozens of five-figure settlements from all the local small businesses that have ever used a fax machine.

NPEs can waste a company’s valuable time and resources with lawsuits, yet also bring value to their patent portfolios by energizing a patent sales and licensing market. There are unscrupulous NPEs, but it’s hardly the black and white situation that some media outlets are depicting.

What did PwC say about trolls?

Well, the PwC study looked at the success rates and awards of patent litigation decisions. One conclusion is that damages awards for NPEs averaged more than triple those for practicing entities over the last four years. We’ll come back to this statistic.

Another key observation is that NPEs have been successful 25% of the time overall, versus 35% for practicing entities. This makes sense because of the burden of proof the NPEs carry as a plaintiff at trial and the relative lack of success for NPEs at summary judgment. However, PwC’s report states that both types of entities win about two-thirds of their trials.

But what about this “67% of all patent trials are initiated by trolls” discussion?

The 67% number comes from the RPX Corporation’s litigation report (produced January 2014) that quantified the percentage of NPE cases filed in 2013 as 67%, compared to 64% in 2012, 47% in 2011, 30% in 2010 and 28% in 2009.

PwC refers to the RPX statistics to accentuate that this new study indicates that only 20% ofdecisions in 2013 involved NPE-filed cases, so the general conclusion would be that NPE cases tend to settle or be dismissed prior to a court’s decision. Admittedly, this is indicative of the prevalent “spray and pray” strategy where NPEs prefer to collect many settlement checks from several “targets” and avoid the courtroom.

In this study, who else is an NPE?

If someone were looking to dramatize the role of “trolls,” the name can be thrown around liberally (and hurtfully) to anyone who owns and asserts a patent without offering a product or a service. For instance, colleges and universities fall under the NPE umbrella as their research and development often ends with a series of published papers rather than a marketable product on an assembly line.

In fact, PwC distinguishes universities and non-profits from companies and individuals within their NPE analysis, with only about 5% of the NPE cases from 1995 to 2013 being attributed to universities and non-profits. Almost 50% of the NPE cases are attributed to an “individual,” who could be the listed inventor for the patent or a third-party assignee.

The word “troll” is obviously a derogatory term used to connote greed and hiding (under a bridge), but the term has adopted a newer, meme-like status as trolls are currently depicted as lacking any contribution to society and merely living off of others’ misfortunes and fears. [Three Billy Goats Gruff]. This is not always the truth with NPEs (e.g., universities).

No one wants to be called a troll—especially in front of a jury—so we’ve even recently seen courts bar defendants from referring to NPEs as such colorful terms as a “corporate shell,” “bounty hunter,” “privateer,” or someone “playing the lawsuit lottery.” [Judge Koh Bans Use Of Term ” Patent Troll” In Apple Jury Trial]

Regardless of the portrayal of an NPE, most people in the patent world distinguish the “trolls” by the strength of the patent, merits of the alleged infringement and their behavior upon notification. Often these are expressed as “frivolity” of the case and “gamesmanship” of the attorneys. Courts are able to punish plaintiffs who bring frivolous claims against a party and state bar associations are tasked with monitoring the ethics of attorneys. The USPTO is tasked with working to strengthen the quality of patents.

What’s the take-away from this study regarding NPEs?

The study focuses on patent litigation that produced a decision, therefore the most important and relevant conclusion is that, over the last four years, average damages awards for NPEs are more than triple the damages for practicing entities. Everything else in these articles, such as the initiation of litigation by NPEs, settlement percentages, and the general behavior of patent trolls is pure inference beyond the scope of the study.

This may sound sympathetic to trolls, but keep in mind that the study highlights that NPEs have more than triple the damages on average compared to practicing entities and it is meant to shock the reader a bit. One explanation for this is that NPEs are in the best position to choose the patents they want to assert and choose the targets they wish to sue—especially when the NPE is willing to ride that patent all the way to the end of a long, expensive trial. Sometimes settling is not an option. Chart 2b indicates that the disparity in the damages awarded to NPEs relative to practicing entities has always been big (since 2000), but perhaps going from two-fold from 2000 – 2009 to three times as much in the past 4 years indicates that NPEs are improving at finding patents and/or picking battles to take all the way to a court decision. More than anything, this seems to reflect the growth in the concept of patents as a business asset.

The PwC report is chock full of interesting patterns and trends of litigation results, so it’s a shame that the 67% number makes the headlines—far more interesting are the charts comparing success rates by 4-year periods (Chart 6b) or success rates for NPEs and practicing entities in front of a jury verusin front of a bench (Chart 6c), as well as other tables that reveal statistics for specific districts of the federal courts. Even the stats that look at the success rates of each type of NPE are telling because the reader sees that universities and non-profits have a higher success rate than non-practicing companies or individuals.

What do we do about the trolls?

The White House has recently called for Congress to do something about the trolls as horror stories of scams and shake-downs are shared. A bill was gaining momentum in the Senate, when Senator Leahy took it off the agenda in early July. That bill had miraculously passed 325-91 in the House and President Obama was willing to sign it if the Senate were to pass it. The bill was opposed by trial attorneys, universities, and bio-pharmaceutical businesses who felt as though the law would severely inhibit everyone’s access to the courts in order to hinder just the trolls. Regardless, most people think that the sitting Congressmen merely wanted a “win” prior to the mid-term elections and that patent reform is unlikely to reappear until next term.

In the meantime, the Supreme Court has recently reiterated rules concerning attorney fee-shifting on frivolous patent cases, as well as clarifying the validity of software patents. Time will tell if these changes have any effects on the damages awards that PwC’s study examined or even if they cause a chilling of the number of patent lawsuit filings.

Furthermore, new ways to challenge the validity of asserted patents have been initiated via the America Invents Act. For example, the Inter Partes Review (IPR) has yielded frightening preliminary statistics as to slowing, if not killing, patents that have been asserted in a suit. While these administrative trials are not cheap, many view these new tools at the Patent Trial and Appeals Board as anti-troll measures. It will be interesting to watch how the USPTO implements these procedures in the near future, especially while former Google counsel, Acting Director Michelle K. Lee, oversees the office.

In the private sector, Silicon Valley has recently seen a handful of tech companies come together as the License on Transfer Network, a group hoping to disarm the “Patent Assertion Entities.” Joining the LOT Network comes via an agreement that creates a license for use of a patent by anyone in the LOT network once that patent is sold. The thought is that the NPEs who consider purchasing patents from companies in the LOT Network will have fewer companies to sue since the license to the other active LOT participants will have triggered upon the transfer and, thus, the NPE will not be as inclined to “troll.” For instance, if a member-company such as Google were to sell a patent to a non-member company and an NPE bought that patent, the NPE would not be able to sue any members of the LOT Network with that patent.

Other notes

NPEs are only as evil as the people who run them—that being said, there are plenty of horror stories of small businesses receiving phantom demand letters that threaten a patent infringement suit without identifying themselves or the patent. This is an out-and-out scam and a plague on society that results in wasted time and resource, and inevitably higher prices on the consumer end.

It is a sin and a shame that patent rights can be misused in scams and shake-downs of businesses around us, but there is a reason that U.S. courts are so often used to defend patent rights. The PwC study, at minimum, reflects the high stakes of the patent market and perhaps the fragility. Nevertheless, merely monitoring the courts may not keep the trolls at bay.

I’d love to hear your thoughts.

III. Large-scale analysis finds majority of clinical trials don’t provide meaningful evidence

Ineffective TreatmentsMedical Ethics • Tags: Center for Drug Evaluation and ResearchClinical trialCTTIDuke University HospitalFDAFood and Drug AdministrationNational Institutes of HealthUnited States National Library of Medicine

04 May 2012

DURHAM, N.C.— The largest comprehensive analysis of ClinicalTrials.gov finds that clinical trials are falling short of producing high-quality evidence needed to guide medical decision-making. The analysis, published today in JAMA, found the majority of clinical trials is small, and there are significant differences among methodical approaches, including randomizing, blinding and the use of data monitoring committees.

“Our analysis raises questions about the best methods for generating evidence, as well as the capacity of the clinical trials enterprise to supply sufficient amounts of high quality evidence to ensure confidence in guideline recommendations,” said Robert Califf, M.D., first author of the paper, vice chancellor for clinical research at Duke University Medical Center, and director of the Duke Translational Medicine Institute.

The analysis was conducted by the Clinical Trials Transformation Initiative (CTTI), a public private partnership founded by the Food and Drug Administration (FDA) and Duke. It extends the usability of the data in ClinicalTrials.gov for research by placing the data through September 27, 2010 into a database structured to facilitate aggregate analysis. This publically accessible database facilitates the assessment of the clinical trials enterprise in a more comprehensive manner than ever before and enables the identification of trends by study type.

 

The National Library of Medicine (NLM), a part of the National Institutes of Health, developed and manages ClinicalTrials.gov. This site maintains a registry of past, current, and planned clinical research studies.

“Since 2007, the Food and Drug Administration Amendment Act has required registration of clinical trials, and the expanded scope and rigor of trial registration policies internationally is producing more complete data from around the world,” stated Deborah Zarin, MD, director, ClinicalTrials.gov, and assistant director for clinical research projects, NLM. “We have amassed over 120,000 registered clinical trials. This rich repository of data has a lot to say about the national and international research portfolio.”

This CTTI project was a collaborative effort by informaticians, statisticians and project managers from NLM, FDA and Duke. CTTI comprises more than 60 member organizations with the goal of identifying practices that will improve the quality and efficiency of clinical trials.

“Since the ClinicalTrials.gov registry contains studies sponsored by multiple entities, including government, industry, foundations and universities, CTTI leaders recognized that it might be a valuable source for benchmarking the state of the clinical trials enterprise,” stated Judith Kramer, MD, executive director of CTTI.

The project goal was to produce an easily accessible database incorporating advances in informatics to permit a detailed characterization of the body of clinical research and facilitate analysis of groups of studies by therapeutic areas, by type of sponsor, by number of participants and by many other parameters.

“Analysis of the entire portfolio will enable the many entities in the clinical trials enterprise to examine their practices in comparison with others,” says Califf. “For example, 96% of clinical trials have ≤1000 participants, and 62% have ≤ 100. While there are many excellent small clinical trials, these studies will not be able to inform patients, doctors and consumers about the choices they must make to prevent and treat disease.”

The analysis showed heterogeneity in median trial size, with cardiovascular trials tending to be twice as large as those in oncology and trials in mental health falling in the middle. It also showed major differences in the use of randomization, blinding, and data monitoring committees, critical issues often used to judge the quality of evidence for medical decisions in clinical practice guidelines and systematic overviews.

“These results reinforce the importance of exploration, analysis and inspection of our clinical trials enterprise,” said Rachel Behrman Sherman, MD, associate director for the Office of Medical Policy at the FDA’s Center for Drug Evaluation and Research. “Generation of this evidence will contribute to our understanding of the number of studies in different phases of research, the therapeutic areas, and ways we can improve data collection about clinical trials, eventually improving the quality of clinical trials.”

IV.  Lawmakers urge CMS to extend MU hardship exemption for pathologists

 

Eighty-nine members of Congress have asked the Centers for Medicare & Medicaid Services to give pathologists a break and extend the hardship exemption they currently enjoy for all of Stage 3 of the Meaningful Use program.In the letter–dated July 10 and addressed to CMS Administrator Marilyn Tavenner–the lawmakers point out that CMS had recognized in its 2012 final rule implementing Stage 2 of the program that it was difficult for pathologists to meet the Meaningful Use requirements and granted a one year exception for 2015, the first year that penalties will be imposed. They now are asking that the exception be expanded to include the full five-year maximum allowed under the American Recovery and Reinvestment Act.

“Pathologists have limited direct contact with patients and do not operate in EHRs,” the letter states. “Instead, pathologists use sophisticated computerized laboratory information systems (LISs) to support the work of analyzing patient specimens and generating test results. These LISs exchange laboratory and pathology data with EHRs.”

Interestingly, the lawmakers’ exemption request is only on behalf of pathologists, even though CMS had granted the one-year hardship exception to pathologists, radiologists and anesthesiologists.

Rep. Tom Price (R-Ga.), one of the members spearheading the letter, had also introduced a bill (H.R. 1309) in March 2013 that would exclude pathologists from the incentives and penalties of the Meaningful Use program. The bill, which has 31 cosponsors, is currently sitting in committee. That bill also does not include relief for radiologists or anesthesiologists.

CMS has provided some flexibility about the hardship exceptions in the past, most recently by allowing providers to apply for one due to EHR vendor delays in upgrading to Stage 2 of the program.

However, CMS also noted in the 2012 rule granting the one-year exception that it was granting the exception in large part because of the then-current lack of health information exchange and that “physicians in these three specialties should not expect that this exception will continue indefinitely, nor should they expect that we will grant the exception for the full 5-year period permitted by statute.”
