Patrick Sandoval

Patent Agent
248.524.2300, ext. 6136

Patrick Sandoval is a registered patent agent with extensive experience in drafting patent applications for electrical, electromechanical, and computer science fields. Prior to joining the firm, he has worked as a Patent Examiner, a Patent and Engineering Consultant to a leading Korean law firm, and a hardware engineer at a high-speed satellite internet service company.

Patrick chose a career as a patent agent so as to lean on his expertise in guiding inventors through the patent process. As a former engineer, he easily connects with inventors from a variety of industries. Patrick leverages his years of experience at the USPTO in all phases of the patent drafting and prosecution process on behalf of U.S. and international clients, with a great familiarity of what expedites patent prosecution, reduces the amount of unnecessary non-prior art rejections, and secures a broader claim scope for his clients.

Patrick is well versed in in tailoring patent prosecution strategies according to client interests, whether it involves securing allowance through minimal clarifying amendments or a more aggressive approach. With inventors, he is versed at leading them to expand on their innovations, resulting in a product that has the potential to increase revenue and provide greater overall protection.

Patrick’s clients’ technologies have included mobile device applications, multimedia communication, medical treatment programs and healthcare management, medical devices and systems (surgical tools, robotic assisted surgery, computer vision and object tracking, imaging, software programs and GUIs), network security (threat analysis and detection, data encryption, and system analysis), scalable architectures for web functionality, sensors and performance monitoring, workforce management platforms, automotive electronics and vehicle diagnostics, electronic gaming machines, GPUs, DPUs, networking architectures and protocols, user/device authentication in association with financial transactions, telecommunications (5G, LTE, WLAN, D2D, V2X) and telecommunications standards (3GPP), satellite systems, and artificial intelligence (AI)/machine learning applied to various applications.

Patrick previously worked with a leading intellectual property law firm in South Korea for five years, where he assisted with drafting and prosecution matters for both their overseas and patent departments and provided counseling and in-house training sessions to Korean patent attorneys regarding U.S. patent prosecution. Through his experiences in the US and abroad, he is particularly skilled at helping clients understand the nuances of protection strategies related to different regions.

In addition to his patent experience, Patrick worked as a hardware engineer with a high-speed satellite internet service company, specializing in analog ASIC design, fabrication, and testing.

Giving back to the community is important. Patrick has prior experience with Mi Casa Resource Center’s ProBoPat Program, providing low-income inventors with patent preparation and prosecution legal services. Though currently busy raising two toddlers with his wife, Patrick looks forward to contributing to similar pro bono opportunities.

In his past life outside of patents and engineering, Patrick was dancer and dance instructor, and he has previously performed with the Kennedy Center’s Imagination Celebration on tour. Though he no longer teaches professionally, he does enjoy participating in impromptu dance performances with his kids at home.
