Los Altos Law is a boutique law firm specializing in IP (intellectual property) protection, licensing, and enforcement. We have extensive experience in both litigation and patent prosecution. This helps you, 1st, because we have a better idea of what might happen to your patent when it "hits the streets", and 2nd, because we have a better idea of looking for weaknesses in adverse patents. Languages we speak include "engineer," "legalese," and "startup investing."
Los Altos Law also advise on other matters besides patents. This includes trademarks, copyright, trade secrets, data privacy and security, the growing field of internet law, and of course, IP issues relating to artificial intelligence (AI) and machine learning. We help with understanding and support about the growing collection of AI and internet security regulations which are currently being put in place.
