Patent Interference Lawyers

Patent Interference Lawyers - Sunnyvale

A Patent Interference is a type of dispute that arises between two patent owners each of whom has a patent that claims the same invention. [1] Our affordable approach for pursuing patent interference proceedings for our clients is described here and could be just what you're looking for.

Our founder, Chris Maiorana provides many critical insights regarding patent interference proceedings here. An appeal of an interference ruling regarding patents claiming the same integrated circuit etching invention is described in an IPLaw360 article from 2014. The Federal Circuit affirmed the Patent Trial and Appeal Board (PTAB) decision for most of the claims and the broadest claims in contention that Tony Chiang’s (affiliated with Applied Materials Inc.) patent was entitled to an earlier priority date than a patent filed by Robert Rozbicki (affiliated with Lam Research Corp.). However, the Federal Circuit did reverse the PTAB finding against Rozbicki’s claims that included a limitation regarding a ration of the etching of a wafer to its deposited elements indicated that these claims in the Rozbicki patent would survive the interference proceeding.

In Patent Interference and many other matters, Maiorana, P.C. has established a reputation as a top patent law firm by providing unsurpassed value for its clients since 1998. Because so many of our clients are key Silicon Valley technology market participants in key computer, software and semiconductor segments, we took action to enhance our responsiveness for our Northern California, San Francisco, and Silicon Valley clients by adding an office in San Jose, CA during the month of May of this year.

To provide even greater responsiveness to our Silicon Valley and Bay Area clients the firm has recently added a San Jose office. We chose San Jose as the location for our second office because of the large number of clients located in our near Silicon Valley (including Sunnyvale) who we believe can benefit greatly from our services.

According to Crunchbase there are more than 1240 companies in Sunnyvale including publicly owned technology companies and compelling pre-IPO ventures. We look forward to enabling the continued success of such publicly owned companies and to charting new horizons for many exciting new ventures. Our San Jose office patent attorneys can readily schedule in-person interviews with examiners in the Silicon Valley US Patent and Trademark Office. Please consider how we can best serve your needs.

Our Sunnyvale interference attorneys have demonstrated their skill and discipline to fight to obtain rights for your key innovations by acquiring more than 1,700 issued US patents for our clients. We are also uniquely positioned to guide you to use those rights for the competitive advantage you deserve.

If your inventions are utilized in a mature market with substantial revenues, our patent licensing experience can help you evaluate whether your rights are likely to withstand licensing and litigation challenges that typically arise when attempting to prevent others from practicing inventions without your authorization. We also have experience as patent license agreement negotiators to make sure that you receive fair value from licensees for your inventions. Please note that as your rights withstand pre-litigation challenges as well as litigation challenges they become powerful tools to protect your profit margins as you meet your market share and technology objectives.

Maiorana P.C. provides exceptional value by aligning our efforts with our clients’ dynamic need to address ever-changing competitive landscapes. We will now be able to readily conduct in-person meetings in our Northern California office with our clients to discuss: patent application preparation (both provisional and non-provisional), patent prosecution, patent licensing, interference proceedings, licensing opportunities and strategies, Inter Partes Review proceeding, contractual matters - including licensing rights, indemnification obligations, and confidentiality obligations, invention disclosure evaluations, patent litigation support, patent opinion letters (invalidity and non-infringement), freedom to operate prior art searches, brainstorming sessions, and many other intellectual property issues related to patents, trademarks, mergers and acquisitions due diligence, trade secrets, and copyrights.
