Among members of the news media, patents have been a popular whipping boy when contemplating why Americans pay higher drug prices relative to the rest of the world. Meanwhile, the Chinese national government extended the period of exclusivity on pharmaceutical patents from 20 years up to 25 years. While China makes moves to embrace further innovation in the pharmaceutical sector by extending exclusivity for drug developers, the United States has evidenced an incredible amount of skepticism regarding the activities of pharmaceutical patent owners trying to protect their property.

The price-tag for non-innovative drug patents, such as these second-wave Restasis patents, is substantial. Indeed, one cannot help but question Allergan’s true motivations for attempting to evade PTAB scrutiny of these patents by reliance on Tribal Immunity based on its deal with the St. Regis Mohawk Tribe. The PTAB, unlike the examiner corps, does have the ability to consider rebuttal expert testimony, and is thus not-so handicapped in its capacity to vet drug patents of questionable validity, with aplomb.

Ever since the Supreme Court decided KSR v. Teleflex, it has been appropriate to reject a patent claim because it was obvious to try. If twice the dose intravenously, half as often works, why wouldn’t the highly-educated person of skill in the art – who would hold an M.D. or Ph.D. level education with years of experience – not be tempted to try the same thing subcutaneously? And if they do try it and the results are as expected that should mean, under KSR, that the claimed invention is obvious. Somehow in the pharmaceutical arts KSR does not get applied that way.

Nothing in my own experience leads me to believe that the PTO applies a lower anticipation or obviousness standard to pharmaceuticals, and I expect this would be news to my colleagues in the industry too. I do, however, often get questions from policymakers, journalists, and others who have been misinformed and led to believe that pharmaceutical companies are re-patenting old drugs to keep prices high, and that our industry is spending “too much” effort on trivial modifications to old medicines rather than creating new ones. Be assured – there is no such thing as “re-patenting,” and our industry is spending plenty on true innovation – but Dr. Michelsohn is certainly raising a fashionable complaint. Public debate by and large seems to have accepted that any given smartphone model is covered by hundreds of patents, but when a complex pharmaceutical product is covered by more than one patent there’s immediate scrutiny and concern.

If a drug company plants a more than 100-patent thicket to protect market exclusivity, then it had better be able to justify why it should deserve the cumulative protection of patent term. Yes, the patent on the original formulation will fall into the public domain and may be capable of being made by generics long before the last of the patents expire, but often-times those follow on “innovations” are the kind of trivial advances that ordinarily shouldn’t support a fresh patent.

Despite the difficulties, the private sector is far and away the best bet for developing the desperately needed medicines of the future. Government is a critical partner and can fund research at our universities and federal laboratories that can’t be done anywhere else. It can also remove some, but not all of the risk inherent in developing treatments for diseases lacking sufficient market size and stability to attract traditional investment. But it still requires a company willing to assume the burden of transforming a discovery into a product that can alleviate suffering.

The European Union suffers from an investment deficit relative to other industrialized nations. A recent report by the European Commission emphasizes this impact, “the EU needs to put in place better incentives and conditions for businesses to innovate” in important areas such as market regulations, intellectual property rights protection, barriers to entrepreneurship, and ease of doing business. Given this, encouraging investment is essential to future growth. Weakening the IP incentives embedded in SPCs would be a step in the wrong direction.

Celgene faces a new gang of generics moving in on its blockbuster Revlimid®.  Over the past year, a number of generics have filed ANDAs against Revlimid®, including Dr. Reddy’s, Zydus, Cipla, and Lotus Pharmaceutical.  Those ANDAs have triggered corresponding Hatch-Waxman lawsuits from Celgene.  Among the asserted patents, most of them expire by 2022, with the exception of two polymorph patents that could extend Revlimid® monopoly until 2027.  The lawsuits are in their early stages, but an upcoming Markman hearing in the case against Dr. Reddy’s is shaping up to be critical to whether Celgene can protect is Revlimid® monopoly past 2022.

In the case, Amgen v. Sanofi, the Court vacated an injunction Amgen obtained against a competing drug to its new PCSK9-inhibitor.  The Court’s decision turned on a finding that the jury was improperly instructed on the criteria for invalidating a patent directed to an antibody for lack of written description.  Thus, will the precedent recently established in Amgen’s PCSK9 case doom the validity of its patents covering Enbrel®?  There are likely two ways that the decision in Amgen v. Sanofi made a validity challenge to Enbrel®’s patents easier.

Novartis has agreed to acquire French radiopharmaceutical firm Advanced Accelerator Applications (AAA) in a deal which values AAA at $3.9 billion USD. The deal, funded through short- and long-term debt, adds the radioligand therapy (RDL) known as Lutathera to the Novartis pipeline. This drug, approved for use in the European Union and currently undergoing trials for approval by the U.S. Food and Drug Administration (FDA), is used in the treatment of patients suffering from neuroendocrine tumors.

On Thursday, October 12th, a pair of letters addressed to the bipartisan leadership of the Senate Judiciary Committee were delivered in an attempt to inform Senators on that committee of various issues in play regarding the recent patent deal between multinational pharmaceutical firm Allergan and the sovereign St. Regis Mohawk Tribe. The two groups sending the letters represent stakeholders in the U.S. patent system coming from very different backgrounds who realize that there are fundamental flaws in the system created by inter partes review (IPR) proceedings which are carried out at the Patent Trial and Appeal Board (PTAB).

On Thursday, September 28th, a judge in the District of Delaware entered an order stipulating dismissal in a patent infringement case brought by North Chicago-based pharmaceutical firm AbbVie (NYSE:ABBV) against Thousand Oaks, CA-based drugmaker Amgen (NASDAQ:AMGN). According to reports, the settlement follows an agreement between the two companies to delay a generic version of the anti-inflammatory drug Humira from the U.S. market until 2023… Of AbbVie’s total $6.94 billion in net revenues from U.S. and international sales during the quarter, Humira contributed $4.71 billion in revenues.

While the Patent Trial and Appeal Board (PTAB) has not been friendly to patent owners, to put it mildly, the PTAB has not been inhospitable to pharma patent owners according to a report issued in mid-June by BiologicsHQ, a searchable database of drugs, patents, and companies involved in PTAB inter partes review (IPR) proceedings developed by attorneys at Fitzpatrick, Cella, Harper & Scinto. The BiologicsHQ report shows a much different story in terms of drug patents facing IPR challenges at the PTAB. The report looks at a combination of data sources, including the Orange Book, Center for Drug Evaluation and Research (CDER) listed biologics and statistics on America Invents Act (AIA) trials published by the PTAB. The BiologicsHQ report draws the conclusion that, despite widespread concerns about the PTAB operating as a patent death squad in IPRs, “such concern is not justified for drug patents.”

IP-skeptics charge that these inventions are little more than a way for pharmaceutical companies to cynically prolong patent life and maximize profits, without providing any meaningful innovation. This rather simplistic view misunderstands how the patent system works, and the role of patents in incentivizing drug discovery and development. In reality, many of today’s most significant medicines owe their existence to the ability of medical innovators to secure patents for novel new forms and new uses of existing treatments.
