Performing a Service without Selling the Process Still Triggers the On-Sale Bar

May 24, 2019 | Blog | By Daniel Weinger, Will Perkins, Kristina Cary, Serge Subach

Services play a large role in today’s economy, and it is important to be mindful of how certain pitfalls that apply to product-based intellectual property rights also apply to method or process-based intellectual property (“IP”) rights.  For example, the “on-sale bar” invalidates a patent on a product where a sale or offer to sell the product occurred more than a year prior to filing for a patent.
Viewpoint General
Just about every emerging business/start-up lawyer could write a book (and many have!) on the topics of equity division, incorporation and the innumerable ‘other details’ founders need to keep in mind when starting a business!
