SLIDE 4 under Fed. R. Evid. 702. Indeed, where an issue calls for consideration of evidence from the perspective of one of
- rdinary skill in the art, it is contradictory to Rule 702 to
allow a witness to testify on the issue who is not qualified as a technical expert in that art. The Federal Circuit ac- knowledged that patent lawyers are often qualified to testify as technical experts, but stated that such a qualification must derive from a lawyer's technical qualifications in the pertinent art. In this case, De- Monte had failed to demonstrate any possible rele- vancy or reliability of the attorney’s testimony in light
- f his lack of relevant technical experience.
At the same time, the Federal Circuit determined that even without the testimony of DeMonte’s patent attorney expert, claim 1 of the ’109 patent was invalid because there were no underlying factual issues in dispute as to
- bviousness. The Federal Circuit said that the technol-
- gy was simple and that neither party claimed that ex-
pert testimony was required to support such a holding. The Federal Circuit criticized the district court’s misun- derstanding of a reference as “prior art outside of the truck environment which used segmented tarps,” and compared the disputed combination to the combination in KSR stating that the segmented truck cover claimed in the ’109 patent represents the “mere application of a known technique to a piece of prior art ready for the improvement.” The Federal Circuit also noted that the secondary considerations of nonobviousness, consid- ered by the district court, could not overcome the strong prima facie case of obviousness. Accordingly, the Federal Circuit held that the ‘109 patent is invalid for
Sundance sued DeMonte for infringement of U.S. Pat- ent No. 5,026,109, directed to a segmented cover sys-
- tem. The jury found claim 1 infringed but invalid for
- bviousness. The court granted Sundance’s motion
for judgment as a matter of law (JMOL) that the ’109 patent was not invalid. DeMonte moved for reconsid- eration in light of KSR and moved for JMOL of nonin-
- fringement. The court denied both motions, and De-
Monte appealed. This summary will address two issues: 1) the district court’s admission of DeMonte’s expert witness testi- mony; and 2) the district court’s grant of the JMOL
- verturning the jury verdict of obviousness.
One of Demonte’s experts, a patent attorney, pre- pared an expert report on the issued of USPTO prac- tice and procedures, claim construction, noninfringe- ment, invalidity and inequitable conduct. Sundance filed a motion in limine to preclude the attorney’s tes- timony because he lacked the appropriate technical background in the field of the invention. Demonte conceded that the attorney did not have experience with the relevant technology but argued that his quali- fications would be an appropriate subject for cross- examination and would go to the weight of his testi-
- mony. The district court denied the motion and al-
lowed the attorney to testify. The Federal Circuit held that it is an abuse of discre- tion to permit a witness to testify as an expert on the issues of noninfringement or invalidity unless that wit- ness is qualified as an expert in the pertinent art. Tes- timony proffered by a witness lacking the relevant technical expertise fails the standard of admissibility
