Motions to Amend in Inter Partes Review: Why did Ethicon Cut Against the Grain?

Attorney: Todd W. Baker
December 9, 2019

Motions to amend (MTAs) are generally disfavored. The prevailing approach calls for patentees to file an MTA in Inter Partes Review (IPR) only in limited circumstances. In particular, most patentees are moving to narrow or clarify claim scope via an MTA only in cases where (i) there is no related application pending at the Office and (ii) the specter of lost past damages due to intervening rights outweighs the risk of an invalidity finding. At first glance, neither (i) nor (ii) appears to be true in the case of Intuitive Surgical, Inc. v. Ethicon, LLC, (IPRs2018-00933, 00934, and 00935), yet Ethicon elected to pursue an MTA in each of the IPRs and was successful in doing so.... Read more

The Flip Side of Reasonable Expectation of Success is Unpredictability

Attorney: Daniel J. Pereira, Ph.D.
October 11, 2019

The Federal Circuit in a precedential opinion in Osai Pharmaceuticals, LLC v Apotex et al (Fed. Cir., October 4, 2019) reversed the USPTO's determination of obviousness in an IPR for patent claims directed to the treatment of non-small cell lung cancer (NSCLC). Just reading the background of the first three or four pages of the decision, it was already apparent that the Court was not going to be affirming the PTAB's decision. Notably:... Read more

SOVEREIGN IMMUNITY AND IPR'S: AND NOW, THE REST OF THE STORY

Attorney: J. Derek Mason, Ph.D., CLP
June 14, 2019

Radio great Paul Harvey would always leave listeners hanging during his broadcast, then return from a commercial with "the rest of the story". Previously, I wrote on the Federal Circuit ruling with respect to Tribal Immunity (https://www.oblon.com/publications/tribal-immunity-in-ipr-is-dealt-a-death-blow-by-the-federal-circuit). At the end of that article I stated: "I note, however, that in the final sentence of their analysis, the Federal Circuit explicitly stated that this decision did NOT address whether there is any reason to treat state sovereign immunity differently with respect to IPR proceedings. That will remain to be seen…"... Read more

Written Description In Provisional Application: Perdue Pharma L.P. v. Andrei Iancu.

Attorney: Marina I. Miller, Ph.D.
May 28, 2019

Amneal Pharmaceuticals, LLC. ("Amneal") filed two petitions for inter partes review of claims 1–13 and 16–19 of U.S. Patent No. 9,034,376 ("the '376 patent") of Purdue Pharma L.P., P.F. Laboratories, Inc. and Purdue Pharmaceuticals L.P. ("Purdue"). In the petitions, Amneal argued that claims 1–13 and 16–19 were unpatentable for obviousness over the combinations of multiple prior art references including US 2002/0187192 A1 ("Joshi")....

PTAB Issues Two New Precedential Opinions On Discretion to Deny Review - Implications for Generics

Attorney: Lisa M. Mandrusiak
May 9, 2019

The PTAB designated two decisions as precedential this week (in addition to several in previous weeks), both relevant to the Board's discretion to deny review. These cases illustrate that the PTO is in the process of designating precedential opinions on a number of issues, in line with revised Standard Operating Procedure 2 for designating precedential and informative decisions. See my previous posts on other recent precedential decisions here and here.... Read more

Motions to Amend: Is the PTAB's Lectrosonics Order Just of Western Digital?

Attorney: Todd W. Baker
March 11, 2019

Spring gardening season has begun and the USPTO is once again planting its Motion to Amend ("MTA") seeds. In a substantial redux of Western Digital Corporation v. Spex Technologies, IPR2018-00082,-00084, paper 13, the PTAB this past week designated paper 15 of Lectrosonics v. Zaxcom, IPR2018-01129, 01130("Lectrosonics Order") as an informative decision....

No More IPRs From Generic Drug Makers?

Attorney: Yuki Onoe
February 24, 2019

The USPTO argues that a petitioner who has received a favorable final written decision in an IPR is estopped from reusing the same winning argument in a district court. If the Federal Circuit in BTG International Ltd. v. Amneal Pharmaceuticals LLC, agrees with the PTO, an ANDA sponsor would not take the risk of "winning" at the PTAB and would rather present the best argument in a district court.... Read more

Bioisosterism, by Itself, May Not be Sufficient Motivation to Modify a Lead Compound

Attorney: Stephen G. Baxter, Ph.D.
February 11, 2019

In the recent decision, Mylan Pharmaceuticals Inc. v. Research Corporation Technologies, Inc., the Federal Circuit affirmed the PTAB's finding that Claims 8 to 13 of U.S. Reissue Patent 38,551 ("the '551 patent") owned by Research Corporation Technologies, Inc. ("RCT") are not unpatentable.... Read more
