Representative Experience

Patent services for SanDisk Corporation

Our patent practitioners in the San Francisco office have represented SanDisk since 1988, around the time it was founded, and have helped SanDisk build a patent portfolio that has been widely licensed. SanDisk has received significant annual patent royalties in the last few years from this patent portfolio that our group obtained. A number of patents in this portfolio withstood many challenges by competitors in major ITC and District Court litigation. We continue to help SanDisk in the procurement of their patents. (Ongoing)
