Ribbon’s patent campaign against Metaswitch has a somewhat complicated history, starting with an infringement lawsuit filed in January 2014 under the case name Genband US v. Metaswitch Networks. Genband (Ribbon’s predecessor) asserted its patents against Metaswitch’s Perimeta Session Border Controller, a cloud native carrier-class virtualized SBC, as well as several other Metaswitch products. By today’s patent litigation success standards, Genband fared extremely well in that lawsuit. However, not satisfied with an $8.8 million royalty award after trial in January 2016, which was upheld on appeal and remand, Ribbon (as Sonus Networks) filed two more lawsuits against Metaswitch on March 8, 2018, in the Eastern District of Texas. Collectively Ribbon has asserted infringement of ten more patents against Metaswitch, on top of the seven patents that Metaswitch was found to infringe in 2016.
"We generally believe that most if not all design patents are bunk; designs are already well covered by copyright law and to a certain degree by registered trademarks, e.g. on shapes."Looking at another Eastern District, this time in Michigan up north, the courts too are getting involved. Ellie Mertens wrote that they "recently applied the brakes to the Automotive Body Parts Association's efforts to invalidate Ford’s design patents..."
We wrote about this before. We generally believe that most if not all design patents are bunk [1, 2]; designs are already well covered by copyright law and to a certain degree by registered trademarks, e.g. on shapes.
Anyway, on we proceed to another case. The H2O, Inc v Meras Engineering, Inc. patent case's "verdict was excessive," according to this report about 'damages' being cut by almost three quarters (down from $12.5 million to $3.5 million). To quote the Docket Navigator:
Following a $12.5 million jury verdict for infringement of plaintiff's water system disinfectant patent, the court granted defendants' alternative motion for remittitur, subject to plaintiff's acceptance of a $3.5 million award, because the verdict was excessive.
The court granted plaintiff's motion for pre-judgment interest and rejected defendant's argument that plaintiff was not entitled to any interest because the jury awarded design patent profits under 35 U.S.C. ۤ 289.
The court denied defendant's motion to dismiss on the ground that plaintiff’s signal processing patent encompassed unpatentable subject matter under In re Nuijten, 500 F.3d 1346 (Fed. Cir. 2007).
The court denied in part plaintiff's motion in limine to exclude certain obviousness theories due to IPR estoppel.
The court denied defendant's motion to exclude the testimony of plaintiffs' damages expert regarding a reasonable royalty for failing to apportion damages on a claim-by-claim basis.
