Provisional patent

File a provisional patent application.

A provisional application is a lower-cost first step toward a patent. It gives you up to 12 months to decide whether to pursue a full utility patent application—and prepare for that larger investment.

  • Your approval of the exact materials before filing
  • U.S. filing and verification of the filing receipt

From $249*

*Filing professional fee. Government fees not included.

Utility patent

Apply for a utility patent.

A utility patent protects how your invention works. That protection can help you defend the advantage you’ve created and build a business around your invention.

  • One agreed invention, prepared from your technical materials
  • A written application, claims, abstract, and agreed necessary drawings

From $2,949*

*Essentials professional fee. Government fees not included.

Design patent

Apply for a design patent.

When your product’s appearance helps it stand out, a design patent can help you protect that investment.

  • One design for one product
  • Attorney direction of the appearance claimed and a standard set of formal drawings

From $899*

*Essentials professional fee. Government fees not included.

The experience behind Inventrell

Serious patent experience.
Within reach.

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. 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.

Before you begin

A few common questions.

Which service do I need?

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 I’ll help you decide where to start.

Will I work directly with you?

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.

What happens after I get in touch?

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. I’ll only ask for payment when we’ve agreed on a plan of action.

What do the prices include?

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 preparation starts at $549.

How quickly can you deliver?

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.

What if you need more information from me?

If necessary information or approval is missing, I’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 my side—including delays from any third parties that I work with—remain my responsibility.

Does filing mean I have a patent?

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.”
