Nathan provided an expert report and deposition testimony for the plaintiff in a case related to technologies used in smartphones, addressing the considerations of the parties at the hypothetical negotiation in a Georgia-Pacific analysis, including the analysis of the benefits enabled by the asserted patents and customary industry licensing practices. Following our work, the case settled favorably for our client.

Nathan provided expert reports and testimony at a preliminary injunction hearing for the plaintiff on the issues of irreparable harm, the balance of hardships, and the public interest related to a pharmaceutical patent. The plaintiff’s motion for a preliminary injunction was granted and the case settled favorably for our client.

Our experts advised a private equity investor and performed due diligence relating to the value of an extensive portfolio of cellular infrastructure patents in which the client was considering a significant investment. Based on our analysis, the client ultimately decided to move forward with the transaction.

On behalf of a defendant in a patent infringement suit, we identified an acquisition target patent that enabled the client to file a counterclaim. We negotiated an acceptable transaction price and closed the sale in a matter of weeks. Armed with the acquired patent the defendant was able to settle the litigation on very favorable terms quickly.
