In Helicos Biosciences Corp. v. Pacific Biosciences of California, et al., Civ. No. 10-735-SLR (D. Del. Dec. 16, 2011), Judge Robinson denied a motion to stay litigation pending the outcome of inter partes reexamination proceedings. Id. at 5. Judge Robinson first explained that the status of the litigation was neutral to the Court’s decision—discovery was initiated in March 2011, and was slated to be completed, including expert discovery, by April 2012. Id. at 3. Next, Judge Robinson noted that the “simplification of litigation” factor weighed against granting a stay, because “there is not a complete overlap between those issues to be resolved upon reexamination . . . and the issues to be tried in the case . . .,” especially since the litigation included one patent that was not involved in the reexamination. Id. at 4. Finally, considering potential prejudice resulting from granting a stay, Judge Robinson found that both the timing of the motion to stay (filed approximately eight months after litigation began, three months after the requests for reexamination were filed, and between two weeks and one month after the requests for reexaminations were granted) and the status of the reexaminations (prosecutions of 3 of 4 patents had not yet closed) weighed against granting a stay. Id. at 4-5. Finally, Judge Robinson considered the relationship of the parties, and found that although the Court was not making definitive findings on the issue, the Court was satisfied at this juncture that “Helicos is a market participant . . . such that this factor generally disfavors a stay.” Id. at 6. Judge Robinson noted that the Court’s ruling likely would be different if the same facts were presented in the future: “The Leahy-Smith Act (H.R. 1249) . . . requires courts to automatically stay litigation filed after a petition for reexamination. H.R. 1249 is not yet controlling. While the reexamination was filed after the litigation in this case, the court would likely stay the case if it were subject to the new legislation.” Id. at 3 n.2.
