Learn more about freedom to operateThe experience behind Inventrell

Hi, I’m Parth, a registered patent attorney, Harvard Law graduate, and founder of Inventrell. Earlier in my career, I represented large tech companies—I’ve written patents for Visa and Pixar, and argued in court for Apple and Nintendo. I’ve also worked in the court system, helping judges decide patent cases with millions or billions of dollars on the line.
Those experiences taught me that it’s not just about getting a patent—it’s about getting one that will hold up when you need it: against a motivated competitor in court.
I started Inventrell to bring that perspective—and my personal attention—at a price and speed that work for innovators of any size.
About Inventrell & its founder →Before you begin
A patentability search helps you understand what has already been published. A provisional application can establish an early filing date, while a utility application seeks protection for how your invention works and a design application seeks protection for how your product looks. A freedom-to-operate assessment helps you understand whether someone else’s patent could affect your product. If you’re unsure, choose “I’m not sure yet” in the submission form above and we’ll help you decide where to start.
Yes. I’m Parth Sagdeo, a registered U.S. patent attorney, and I’m your point of contact. Your legal work won’t be handed off to a non-lawyer—I personally handle the legal work included in your package.
Yes. We work with inventors and companies anywhere in the United States, for every service on this site, by email and with calls where your package includes them.
Yes. We work with inventors and companies outside the United States on U.S. patent matters, including searches, U.S. applications, and freedom-to-operate reviews of U.S. patents. Filings in other countries are not included.
I’ll email you personally to discuss what you need and answer your questions. If we decide to work together, you’ll receive a clear description of the work, a fixed price, and a delivery date. We’ll only ask for payment when we’ve agreed on a plan of action.
Each package lists the work included in its professional fee. Government fees are separate, and later work—such as responding to the patent office—is quoted separately. For provisional applications, the $249 Filing package uses an application you prepare; attorney review and filing is $699, and attorney preparation starts at $1,099.
We agree on a delivery date before work begins. The clock starts once the agreed information, engagement, and payment are complete. If our delay causes us to miss that date, we refund 50% of your professional fee.
If necessary information or approval is missing, we’ll tell you in writing when the affected work is paused. If you add work beyond the agreed scope, we’ll agree on any change to the price or delivery date first. Ordinary delays on our side—including delays from any third parties that we work with—remain our responsibility.
Filing an application does not itself give you an issued patent. A provisional application gives you up to 12 months to file a non-provisional patent application, which the Patent Office examines. If the Patent Office approves your application, a patent is issued after the issue fee is paid and any remaining requirements are met. While your application is pending, you can describe products covered by it as “patent pending.”
