PTAB Precedential Decision Designations Continue Patent Owner-Friendly Trend

On May 7, the U.S. Patent and Trademark Office (USPTO) designated two recent decisions of the Patent Trial and Appeal Board (PTAB) as precedential, bringing the number of PTAB decisions declared precedential since the beginning of this March to 11. The recently designated decisions, both of which resulted in the denial of institution in inter partes review (IPR) proceedings, appear to be part of a general trend to designate as precedential patent owner-friendly decisions denying the institution of PTAB trials. The first of these recent precedential designations was NHK Spring Co., Ltd. v. Intri-Plex Technologies, Inc., an IPR proceeding that was denied institution last September. NHK Spring had requested an IPR to challenge the validity of four claims of U.S. Patent No. 6183841, titled Optimized Low Profile Swage Mount Base Plate Attachment of Suspension Assembly for Hard Disk Drive. The patent covers a disk head assembly having a low-profile base plate which addressed a need for increased data storage capacity in hard disk drives.

The Doctrine of Claim Differentiation: Who Got It Right in Retractable Technologies?

Whether the term “body” encompassed “multi-piece” structures became the crux of the claim construction issues in Retractable Technologies. The District Court for Eastern Texas, apparently applying the doctrine of claim differentiation, construed independent Claims 1 and 43 to cover a “body” which might be a “multi-piece” structure. Accordingly, the District Court denied post-trial motions by the alleged infringer (Becton Dickinson or “BD”) to overturn the jury verdict that BD infringed these Claims of the ‘224 patent. Judge Lourie (writing for the panel majority) reversed the District Court, ruling that the term “body” was limited to a “one-piece” structure in light of the ‘224 patent specification.
