US9,148,480 - ON24 asserted this patent against Webinart.net by filing an infringement action in Northern California District Court. Not happy with the performance of their previous patent law firm, Webinar.net retained our firm to take over the defense. We filed a motion requesting a claim construction hearing to construe a term under 35 USC § 112(6) in connection with an invalidity defense under 35 USC § 112(2). ON24 objected to the claim construction for being untimely, forcing the Court to hold a hearing on the issue. During the hearing, Mr. Sheerin argued that claim construction can still occur as part of a Motion for Summary Judgement since the invalidity argument under 35 USC § 112(2) was asserted in the Defendant's original invalidity contentions. The Court agreed with Mr. Sheerin and will proceed with claim construction under 35 USC § 112(6) when deciding Mr. Sheerin's Motion for Summary Judgement.

New claim construction brief and motion for partial summary judgement filed. Response claim construction brief filed. Reply to Plaintiff's response to motion for summary judgement filed. Reply claim construction brief filed.
