The Revival of Phage Therapy to Fight Antimicrobial Resistance (AMR) – Part III: What about patent protection and alternative incentives?

In Part II of this blog on legal issues relating to the revival of phage therapy I discussed the US Supreme Court’s decisions in Myriad and Prometheus, which might present major obstacles to the patentability of phage-related technology (a more detailed analysis of the Myriad and Prometheus decisions is available here).

Yet, all is not lost. As indicated in Part II, Myriad does not directly affect the patentability of synthetically modified biological compounds and Prometheus would still allow patents on inventive applications of natural processes and correlations that add new features to “natural laws”. Thus there still seems to be considerable leeway for patenting within the area of page therapy.

One example, mentioned in a recent Nature article, could be the skillful selection and precise combination of different phages in order to attack one specific type of bacteria. Such selections, however, would face a tough battle to overcome the “additional features that add significantly more” and “not identical” thresholds set by Prometheus and Myriad. Another example with even better prospects for patentability relates to genetically modified phages that are – due to human intervention – enabled to target only specific bacteria. This technology was recently presented by MIT researchers at the 2014 American Society for Microbiology Meeting. The researchers led by Timothy Lu had genetically engineered phages that use a DNA-editing system called CRISPR to target and kill only antibiotic-resistant bacteria while leaving other susceptible cells untouched. The significant engineering and alteration of natural products and processes involved in such inventions would most likely meet both the Myriad and Prometheus standards.

Yet, while the USPTO has recently issued new patent eligibility guidance and the CAFC has begun to directly apply Prometheus and Myriad to reject patent claims in biotech cases (e.g. In re Roslin), many questions remain unsolved. In particular, it is still not sufficiently clear exactly how much modification is required to render a molecule or method sufficiently distinct from naturally occurring product and processes. And even if the patent-eligibility threshold could be met in extraordinarily circumstances, the claimed invention would still have to fulfil other patentability requirements such as novelty, non-obviousness and the written description-requirements. The threshold for these requirements, however, have been heightened in recent years (see e.g. KSR v. Teleflex (2007) , Nautilus (2014) etc.). Considering that phage therapy is almost a century old with a substantial common general knowledge and a state of the art employing routine methods, these crucial requirements might still prevent the patentability of many useful applications.

New regulatory pathways and incentives for sustainable antibiotics: Recent European & US Initiatives

Please find attached a ppt presentation on “New regulatory pathways and incentives for sustainable antibiotics: Recent European & US Initiatives” given on March 7, 2014 at the Broad Institute of MIT and Harvard.  The presentation was followed by a discussion moderated by US patent attorney Melissa Hunter-Ensor, Partner at Saul Ewing, Boston.

I started out by emphasizing increasing problems of antimicrobial resistance (AMR) on a global level, providing new statistics and facts. This was followed by a discussion of main reasons for these alarming developments, such as inappropriate use in agriculture and medicine, insufficient precautions, lack of education, climate change, travel behavior, insufficient collaboration and funding of R&D, scientific complexities, and the problem that incentives provided by the traditional innovation system model often fail in the case of antibiotics.

Next the presentation focused on a variety of solution models that could be discussed to fight AMR. These include both conservational and preventive approaches comprising use limitations, increased public awareness, and better hygiene, but also reactive push & pull strategies, such as increased investments, new collaborative models for R&D in antibiotics, prizes, “sui generis” IP-related incentives, regulatory responses and new pathways for approval.

Feb 28: Ruth Grant speaking to the HMS Division of Medical Ethics


Please join the HMS Division of Medical Ethics and Program in Ethics and Health for…

“Strings Attached: Untangling the Ethics of Incentives”

Ruth W. Grant, PhD

Professor of Political Science and Philosophy, Duke University

Thursday, February 28, 2013

12:00 – 1:15 PM

HMS Division of Medical Ethics

1st Floor Conference Room

641 Huntington Avenue, Boston

A light lunch will be provided. RSVP required to DME@hms.harvard.edu.

Ruth Grant is a Professor of Political Science at Duke University and a Senior Fellow at the Kenan Institute for Ethics, specializing in political theory and political ethics. Her most recent book, Strings Attached: Untangling the Ethics of Incentives, examines moral concerns raised by the pervasive use of incentives to shape behavior. Her seminar talk will propose an ethical framework for thinking about the promises and limits of incentives, including the use of incentives in public health.

A Question of Insurance Fraud?

By Scott Burris

No, I mean it: this is a question to Bill of Health readers who know about the law on this topic.

This week, a colleague handed me a palm card she’d been given at a subway station here in Philadelphia. “Cash for diabetic test strips” it read.  Comparing prices on the company’s website with prices on Wal-Mart’s pharmacy page, it looked like the test-strip buyer pays about 20 cents on the dollar for “pre-owned” test strips.

The palm card and the website both stipulate that the strips be unexpired and in their original, unopened, factory-sealed boxes.

So, one asks, are there enough people out there who buy more diabetic test strips than they need, and are willing to take an 80% loss to ensure they are used by someone else? That seems unlikely.

No Doctor for the Obese?

by Nir Eyal

Yesterday, Boston public radio station WBUR interviewed a Massachusetts primary care physician who refuses to admit new obese patients. She claims that it’s because she lacks proper equipment, but she seems to have mixed motives. Earlier she had admitted that it’s rather because she feels that if they don’t lose the weight, “I’m paying the cost of other people’s choices.” I bet if she lacked the equipment for wheelchair-bound patients, she would go buy it.

In an upcoming post (09/07: update here), Holly Fernandez Lynch, who, along with Glenn Cohen, gets kudus for kicking off this blog, will explain whether it’s legal for doctors to reject obese patients. But before rejecting them becomes the next trend, is it right?

A whopping 35.7% of Americans are obese, and the trend continues upwards. Obesity increases risk for heart disease, stroke, type II diabetes, and various cancers. It costs the system a fortune. We must tackle this problem head on. But conditioning physician access on weight loss is not the way. Continue reading
