Practice Overview

Patent Law

Patent Law

As a registered patent attorney with the United States Patent and Trademark Office, we assist in procuring patents in a number of technologies and arts from simple mechanical devices (e.g., garments, animal leashes, etc.) to complex technologies including software apps, medical devices, contraceptive devices, computer hardware, artificial intelligence, ad-tech, fin-tech, cryptocurrency and silicon wafer annealing devices.

A special note regarding software inventions : The firm has a very good track record in obtaining software patents. Patenting software related arts can be complicated in a post- Alice world. However, with our due diligence and impressive lawyer-ing skills our patent attorney has successfully obtained software patents for our clients in USPTO departments that have repeatedly rejected (and refused to grant) over 95% patent applications. More about subject matter eligibility guidelines are available at USPTO's website.

I have worked with several of the large IP firms including Harness Dickey and Schwegman. I can assure you Chhabra’s IP firm equals and at times exceeded the quality delivered by large firms. In Silicon Valley, a timely investment in IP is always a wise decision. I consider this money extremely well spent and look forward to their representation in the future.
