About Jong Patent Firm

Jong Patent Firm is a full-service patent prosecution firm based in Churchville, New York, serving clients in Rochester, across the United States, and internationally.

Its team brings decades of engineering and patent prosecution experience and reports having obtained hundreds of patents for clients. The firm works with software, machinery, medical devices, optics, consumer products, and other complex technologies, aiming to identify the broadest and most useful aspects of each invention.

Services extend beyond initial filing. Jong Patent Firm assists with global patent protection and foreign filing, PCT and Madrid Protocol applicants entering the U.S. national stage, trade secret safeguards, clearance and litigation-avoidance searches, infringement analysis, IP asset identification, and R&D training or invention-documentation guidance. The firm also lists trademark law among its service areas and discusses patent, trademark, and copyright considerations for inventors, entrepreneurs, content producers, publishers, technology ventures, and start-ups.

Reviewers consistently praise the firm’s patent expertise, detailed specifications, illustrations, and claims. Many describe working with Cheng-Ning Jong as patient, responsive, and transparent, especially for first-time inventors. Several clients mention successful patent grants, broad claims accepted by the U.S. Patent and Trademark Office, and continued work on multiple applications. The firm’s engineering background is repeatedly cited as helping it grasp complex technical subject matter quickly. Some reviewers also note reasonable fees and a practical, educational approach, including involving students in the patent process.

The overall atmosphere is professional, welcoming, and detail-oriented. Clients often describe clear explanations of the patenting process and proactive help defining inventive aspects. the firm’s website emphasizes patent prosecution and global filing, while trademark, copyright, and trade-secret offerings appear more briefly described. Because the practice is based in Churchville, clients outside Western New York would likely rely on remote communication.

Jong clients describe clear, patient assistance for first-time inventors, without repeated complaints about confusing filing guidance. The written feedback praises detailed specifications, drawings, and claims rather than recurring problems with preparation of patent applications.
