Federal Circuit Requiring More Rigorous Proof of Patent Damages
In a string of recent cases addressing reasonable royalty damages, the Federal Circuit has put patent litigators and district courts on notice that they “must carefully tie proof of damages to the claimed invention’s footprint in the marketplace.” ResQNet.com, Inc. v. Lansa, Inc., 2010 U.S. App. LEXIS 2453 at *19 (Fed. Cir. Feb. 5, 2010).
First, in Lucent Techs., Inc. v. Gateway, Inc., 580 F.3d 1301 (Fed. Cir. 2009), the Court sharply criticized evidence on damages and overturned an award of a lump sum royalty of $358 million.
Then, in ResQNet.com, decided last month, the Court overturned a district judge’s award of a 12.5% hypothetical royalty as speculative.
Just last week, Judge Rader, sitting in the district court for the Eastern District of Texas, applied Lucent and ResQNet and excluded the opinion of an expert witness for improperly relying on general royalty rates in the software industry rather than existing licenses to the patents-in-suit and improperly applying the “entire market value rule.” IP Innovation L.L.C. v. Red Hat, Inc., Case No. 2:07-cv-447 (E.D. Tex. March 2, 2010) (Rader, J.).
The one exception to this trend is the December, 2009 decision in i4i L.P. v. Microsoft Corp., 589 F.3d 1246 (Fed. Cir. 2009), in which the Court did not conduct the type of searching review of the evidence that characterizes Lucent and ResQNet. i4i, however, involved only the appeal of a motion to exclude an expert’s testimony because the defendant failed to make a pre-verdict motion for judgment as a matter of law (JMOL) challenging the sufficiency of the evidence of damages. A district court’s decision on a motion to exclude evidence is reviewed under a deferential abuse of discretion standard, and the Court expressly stated that it addressed only the reliability of the expert’s methodology, not his conclusions. The Court also stated that the result may have been different if the defendant had made a timely motion for JMOL and appeared to draw a distinction between the admissibility of an expert opinion and whether that opinion provided a sufficient basis for a damage award.
A full analysis of the opinions is beyond the scope of a blog post, but the cases contain several high-level lessons for patent litigators, including:
