Shielding an Expert Declarant in Patent Reexamination from Deposition in Concurrent Litigation?
Unlike pre-grant patent prosecution, the submission of declaration evidence under 37 CFR 1.131/132 in patent reexamination is not only common, but the norm. This is due to the fact that there are no opportunities to continue patent reexamination via RCE as in pre-grant prosecution. Likewise, amending claims in patent reexamination is problematic as the Patent Holder may surrender past damages under the doctrine of intervening rights. Where a Patent Holder has invested significant time and money in enforcing their portfolio, intervening rights are of paramount concern. As such, convincing the USPTO of patentability without amendment typically requires more than attorney argument, hence the heightened importance of declaration practice in patent reexamination.
A threshold issue in patent reexaminations concurrent with litigation is whether or not the declarant should be the same expert who is expected to testify at trial, or a new expert retained for reexamination purposes only. This decision is affected by several factors, including the risk of two experts taking inconsistent positions and the likelihood that the declarant in the reexamination will be deposed.
