360° Performance

Case

By acquiring a large group of patents originally obtained by Hitachi, Maxell Ltd. amassed a portfolio of over 5000 patents. Maxell has sued multiple technology companies for infringing those patents and, in 2018, obtained a $43 million jury verdict against ZTE for patent infringement. In 2017, Maxell sued Rothwell Figg client Fandango in the Central District of California, accusing its streaming service FandangoNow of infringing seven patents across four different patent families.

Situation

Facing a complex litigation and a large royalty demand, we developed a multi-pronged approach to knock Maxell’s asserted patents out well before trial. Implementing motions challenging patent eligibility, IPRs, and early claim construction simultaneously gave Fandango a path to obtain dispositive rulings efficiently and without having to move immediately forward with discovery in the district court.

Outcome

We invalidated four patents for lack of patentable subject matter after early claim construction and successfully instituted an IPR challenging the validity of a fifth patent. At the same time we obtained early claim constructions that give Fandango a very strong non-infringement defense as to the two remaining patents. With the validity of five of its patents at risk and with adverse claim construction rulings on the others, Maxell agreed to stay the litigation while the validity issues were resolved. The Federal Circuit affirmed the District Court’s decisions invalidating four of the seven patents and the PTAB found the fifth patent invalid. The litigation with respect to the last two patents remains stayed.

Case

Represented Pfizer and Synthon in a Hatch-Waxman lawsuit filed by Teva Pharmaceuticals relating to the drug Copaxone® (glatiramer acetate), one of the most commonly prescribed disease modifying therapies to treat multiple sclerosis.

Situation

Teva alleged infringement of four patents relating to methods of treating relapsing-remitting forms of multiple sclerosis with a 40 mg/mL glatiramer acetate treatment regimen. Over the last ten years, Teva filed approximately 40 different actions in either district court or before the FDA in an attempt to thwart generic competition for its glatiramer acetate products.

Outcome

After a seven day bench trial in the District of Delaware, all four patents at issue were invalidated. On appeal, the Court of Appeals for the Federal Circuit affirmed the decision, paving the way for Pfizer and Synthon to obtain approval from the FDA for their glatiramer acetate 40 mg/mL product.
