What is a Provisional Patent?
A provisional patent application is the official first step in securing legal protection for an invention. It establishes a prioritized filing date with the USPTO (United States Patent & Trademark Office) and grants the inventor 'Patent Pending' status for a 12-month period.
At Wellstronics3D, we specialize in the high-precision 3D Renderings, Technical Drawings and detailed Technical Writing required for USPTO Provisional Patent Applications. Based in the Twin Cities, our team bridges the gap between complex engineering, prototyping and formal patent requirements, ensuring your intellectual property is backed by professional-grade documentation.

What is included in a professional provisional patent filing package?
Our comprehensive package includes high-contrast 2D black-and-white technical drawings derived from 3D CAD models, along with expert technical writing that describes the product’s utility and novel claims. We manage the entire preparation process, ensuring your submission clearly details how the invention works to provide the strongest possible "patent pending" protection.
Can a physical prototype help with the patent application process?
Yes. We can provide functional physical prototypes that demonstrate the product's mechanics alongside your written application. Having a physical model allows for real-world verification of your claims and provides invaluable clarity when transitioning from a provisional filing to a full non-provisional patent application with an attorney.
Do you work with patent attorneys to file the application?
We bridge the gap between engineering and law by working directly with registered patent attorneys to ensure your filing is handled properly. Once the provisional work is complete, we connect you with these legal experts to facilitate the transition into a full non-provisional patent, ensuring your intellectual property is protected throughout the entire development lifecycle.
Why should an engineering firm prepare my patent drawings instead of an illustrator?
Standard illustrators often miss the functional nuances that make an invention "novel." Because we are mechanical engineers, our drawings are built from accurate 3D master models, ensuring every mechanical claim is technically sound and visually precise. This technical accuracy reduces the risk of rejection or "office actions" during the USPTO examination process.
