Guest Post by Profs. Lemley & Ouellette: Fixing Double Patenting

Patent, ,

Guest post by Professors Mark A. Lemley and Lisa Larrimore Ouellette of Stanford Law School.

Two of the most controversial patent law changes of the past year have involved obviousness-type double patenting, which allows applicants to patent obvious variants of their earlier patents by disclaiming the extra term of the later-expiring patent. First, the Federal Circuit held in In re Cellect that patents tied by double patenting must expire on the same day even if one of the patents has received a patent term adjustment (PTA) giving it a more-than-twenty-year term. The en banc denial and pending cert petition in Cellect have attracted substantial interest from amici and commenters. Second, the USPTO proposed that terminal disclaimers include a commitment to not enforce the patent if any claims in the patent to which it is tied are found to be obvious or not novel. Early commentary on the proposal was “overwhelmingly negative.”

In our new draft article, Fixing Double Patenting, we argue that this outcry is unwarranted. (more…)

Fixing Double Patenting: The Procrustean Solution?

Patent, ,

by Dennis Crouch

I recently provided a set of interesting data on the large number of patents that are “at risk” of being invalidated based on the Federal Circuit’s Cellect decision. This post follows up with a discussion of a recent article titled “Fixing Double Patenting” released in draft form by Stanford Professors Mark Lemley and Lisa Larrimore Ouellette. The article takes a critical look at the practice of obviousness-type double patenting in the U.S. patent system.

The Emperor’s New Judgments: Rule 36 and the Invisible Cloth of Patent Law

Patent,

by Dennis Crouch

The Federal Circuit’s practice of issuing no-opinion affirmances under Rule 36 is facing renewed scrutiny in two recent petitions for rehearing en banc. In UNM Rainforest Innovations v. ZyXEL Communications Corp. and Island Intellectual Property LLC v. TD Ameritrade, Inc., the petitioners argue that the court’s use of one-word Rule 36 judgments allowed it to sidestep key legal and factual issues raised on appeal. These petitions highlight ongoing concerns about the Federal Circuit’s frequent use of Rule 36 and its impact on patent law development.  The failure to provide an explanatory opinion is an appellate-procedure issue – the two patentees also argue that the lower tribunal made substantive legal errors.

I don’t see the court as having a truly nefarious reason for its common no-opinion judgments, but the situation does call to mind the ancient fable about the emperor’s new clothes adapted and popularized by Hans Christian Andersen.  (more…)

A few initial thoughts on Loper Bright and the end of Chevron Deference

This is just a first look at how overturning Chevron may impact patent practice. 

In the past, both the USPTO and patent attorneys have largely ignored the larger scope of administrative law, but in recent years USPTO operations have been under tighter control from the White House, and courts have increasingly asked whether the agency is following the rules.  Administrative patent law was truly launched with  the American Invents Act of 2011 and the resulting administrative patent trials by the PTAB — resulting in hundreds of appeals arguing that the USPTO’s procedural approach is an abuse of administrative power.  Importantly, the Supreme Court in Cuozzo Speed Techs. v. Com. for Intell. Prop., 579 U.S. 261 (2016) provided the patent office with Chevron deference for its determinations regarding AIA trials, including issues such as its approach to claim construction.  But Chevron has now been overruled, and many are wanting the Federal Circuit to revisit the USPTO approach.

Although I expect that the outcome (more…)
