Below are excerpts from judicial opinions referencing our work.

“The Board found that [Party’s] commercial success evidence was ultimately “weak”… We reject [Party’s] challenge to the Board’s reasoning…”

Federal Circuit

“Having considered the arguments and evidence…, we agree with Petitioner that Patent Owner has not met its burden of…[showing] commercial success.”


“We credit Dr. McDuff’s testimony and find… that Patent Owner’s insulin glargine patents may have precluded others from entering the market…”


“At the outset, … [Party] does not challenge Dr. McDuff’s qualifications, which the Court finds are substantial.”

Central District of California

“In addition, the Court found Dr. McDuff’s testimony persuasive with respect to the “lack of nexus”…”

District of New Jersey

“Accordingly, we determine that Petitioner presents sufficient evidence to rebut the presumption of nexus between the commercial success… and the claimed method.”


“…Dr. McDuff’s conclusions stem from his expertise in economic markets.”

Northern District of California

“…we do not agree that the [claimed benefits]… are attributable to the claimed method… we credit Dr. McDuff’s opinions, which stand unrebutted…”


“The defendants offered unrebutted testimony from an expert in economics and pharmaceuticals…”

Federal Circuit

“We are persuaded, rather, by Petitioner’s arguments that the blocking patent would have deterred others…”


“The Court notes… that [defendant] has made a substantial showing that the nexus between the commercial success and the [patent] is tenuous as best…”

District Court of New Jersey

“Dr. McDuff testifies that Patent Owner’s asserted evidence… does not represent a strong case… Again, we credit Dr. McDuff’s opinions… ”


“[Party] has demonstrated irreparable injury… Loss of goodwill and market share destroys [Party’s] relationships with its end-use customers that have been developed over decades…”
