Overview

We have a long history of successfully representing both patent holders and patent challengers in proceedings before the US Patent & Trademark Office (USPTO), specifically before the Patent Trial and Appeal Board (PTAB) in cases covering medical devices, consumer electronics, computer technology, chemicals, and pharmaceuticals. Our experience includes doing so in parallel with ongoing litigation in the federal courts and at the International Trade Commission (ITC).

The Leahy-Smith America Invents Act (AIA) has been in effect since September 2012. Mayer Brown was one of the first firms retained and has since been retained to represent clients in more than 100 inter partes review (IPRs) or covered business method (CBMs) proceedings. In those proceedings, Mayer Brown has represented clients from pre-filing counseling all the way through the final oral hearings. We have argued more than 20 final hearings covering more than 45 proceedings and have had more than 50 proceedings go to a final written decision.

We are therefore well-positioned to represent clients in all facets of these trial proceedings, including IPRs, post-grant review (PGR) and the transitional program for covered business method patents (CBM). We are actively representing clients in pending IPR and CBM proceedings, know the rules and practices before the PTAB and have been on the cutting edge of the evolving law related to such proceedings. Where any proceeding has resulted in an appeal to the Federal Circuit, Mayer Brown has handled the appeal.

Experience

  • We are involved in more than 20 IPR and CBM matters.
  • Google v. BE Technologies, LLC. We represent Google as the petitioner in three IPRs challenging the validity of two patents that are being asserted in pending litigation in the Western District of Tennessee against 20 defendants. We successfully obtained stay of all 20 litigations before institution of trial pending resolution of the IPRs. Awaiting decision on trial institution.
  • Various US Airlines. We filed two petitions seeking a CBM patent review of two US patents that were assigned to Loyally Conversion Systems Corporation (LCSC), which filed a lawsuit against 10 airlines in the Eastern District of Texas accusing the airlines’ loyalty programs of infringement. The accused functionality is related to converting loyalty (e.g., hotel) points into other forms of credits (e.g., frequent-flier miles). As part of its representation of Delta Airlines, Frontier Airlines, United Airlines, and US Airways, Mayer Brown analyzed LCSC’s patents, identified key prior art and developed the strategy of filing CBM petitions in view of the financial nature of LCSC’s patents. Along with Mayer Brown’s clients, American Airlines (which Mayer Brown was not representing in E.D. Texas) agreed with this strategy and retained Mayer Brown to represent it at the USPTO.
  • DSM IP Assets B.V. We represent DSM IP Assets B.V., a life sciences and material sciences company, in ten IPR proceedings involving eight patents relating to optical fiber coatings. These cases are significant because they involve some of the first IPRs filed at the PTAB, in which a patent owner was successful in defending the patentability of the substantial majority of the challenged patent claims. In addition, based on our motions, they were the first cases in which the PTAB allowed additional discovery. Also, they are among the first cases involving chemical patents and dealing with the issue of inherency testing of the prior art.
  • Amneal Pharmaceuticals v. Endo Pharmaceuticals. We represent patent owner Endo Pharmaceuticals in two IPRs challenging the validity of two patents asserted against Amneal’s generic ANDA product in co-pending litigation in the Southern District of New York.
  • Vertex Pharmaceuticals, Inc. We acted as lead counsel in an Inter Partes Review (“IPR”) initiated by Ranbaxy Laboratories at the US Patent and Trademark Office, Ranbaxy Laboratories, Ltd. et al v. Vertex Pharmaceuticals, Inc., Case No. IPR2013-00024. This was one of the first IPRs filed in a pharmaceutical patent case. The matter was settled in November 2013.
  • Software Solution Company. We represent a patent owner in a patent infringement litigation and co-pending CBM review challenging the validity of its asserted real estate settlement software patent.
