The Amgen v. Sanofi decision will encourage more biotech innovation—not the other way around.

I have blogged about the Amgen v. Sanofi case several times, and the case has been summarized in my prior posts andelsewhere.  The case pitted two competing PCSK9-inhibitors against one another, and after several years, resulted in cancelling broad patents covering the new class of antibodies.  Whenever there is any case that cancels patents within the pharmaceutical or biotech space, the common knee-jerk retort from some commentators is that the decision will suppress innovation, chill R&D and discourage any investment in life-saving medicine.  In this case, the opposite is true.

Eylea: How do courts solve a problem like a patent thicket?

Senator Warran recently asked what the Patent Office can do about patent thickets. Yet, the courts are in the unique position of having to contend with scores of patents asserted within a single suit.  When a brand pharmaceutical company shows up with 20, 60 or 100 patents in a single suit, those challenges can be exacerbated by orders of magnitude. So, how have courts face this challenge?  Regeneron’s pending patent suit against Mylan over its prospective biosimilar for Eyelea® is an interesting example.

Will Amgen’s PCSK9 loss read-through to patents covering other biologics drugs?

The long-running patent dispute between Amgen ($AMGN) and Regeneron($REGN) and Sanofi over their competing PCSK9-inhibitors (Repatha® and Praluent®) has reached another milestone.  The case also represents another milestone in the changing landscape for patents covering biologic drugs.  The Amgen decision is at least the second district court decision this year that has invalidated biologic antibody patents under the doctrine of enablement.  The earlier decision related to MorphoSys patents asserted against Janssen related to Darzalex®.  The takeaway is clear:  as biologic drugs take up a larger share of the pharmaceutical medications in the U.S., courts are making it harder for drug companies to use overly-broad patents to corner the market on a particular inhibitor.

Will Amgen win another injunction against Regeneron’s Praluent?

Amgen ($AMGN) is about to square off once again against Regeneron ($REGN) and Sanofi over whether Praluent® should be pulled from the market.  Having prevailed at another jury trial earlier this year showing that Amgen’s PCSK9 protein patents are both valid and infringed, Amgen has renewed its bid for a court order enjoining Praluent® from the market.  The injunction hearing is scheduled for June 2019.  Over two years ago, Amgen prevailed after an earlier injunction hearing where the court ordered Praluent® to be barred from the market.  Will Amgen be able to prevail again?

For Amgen’s PCSK9 patent case, is there any read-through from Court’s summary judgment order to the trial?

On January 18, the District Court in Delaware issued an opinion resolving multiple summary judgment motions filed by both parties.  The key takeaway from that decision is that the case is now teed-up for trial beginning on February 19. But the Court didi highlight some key issues likely to be the focus of the trial.

What is Regeneron’s exposure from Novartis’ patent case against blockbuster Eylea®?

Novartis has filed a patent lawsuit against Regeneron seeking damages for sales of Eylea® and Zaltrap®.  On March 19, 2018, Novartis sued Regeneron in the Southern District of New York, White Plains Division, for infringing U.S. Patent No. 5,688,688.  The ‘688 patent claims gene expression constructs for the expression of polypeptides in mammalian cells.  How strong is Novartis’ case, and what is Regeneron’s exposure?

What is the status of Amgen’s PCSK9 patent lawsuit against Regeneron?

Regeneron ($REGN) and Sanofi released positive topline results from their ODYSSEY clinical trial Praluent®.  In addition was the announcement that prices for Praluent® may be cut.  Investors who may have grown skeptical with the new PCSK9-inhibitor class may now be interested again, which may include the pending patent lawsuit between Amgen ($AMGN) and Regeneron.  What is happening in the case?

What is the Dupixent® patent fight among Amgen, Regeneron and Sanofi all about?

Dupixent® is a recently-released drug forecasted to reach $4B in annual sales.  The drug is a co-venture between Regeneron and Sanofi, which also teamed up to launch Praluent®, one of the two available drugs within the new class of PCSK9-inhibitors.  In the case of Praluent®, Amgen brought Regeneron to court arguing that Praluent® infringed Amgen’s patents and thus the drug should be taken off the market.  Once again, Amgen, Regeneron and Sanofi are back in court.  Amgen has squared off against Regeneron and Sanofi and argued that Dupixent® infringes one of Amgen’s patents.
