Sam Sokhansanj Patent Attorney

About Sam Sokhansanj Patent Attorney

Sam Sokhansanj is a Dallas-based patent and trademark attorney whose practice, the Law Office of Sam Sokhansanj, PLLC, sits at the intersection of engineering and intellectual property law. His background is unusual for the field: he worked as a practicing engineer and as a USPTO Patent Examiner before becoming an attorney, and he holds advanced degrees in electrical engineering, biomedical engineering, and mechanical engineering alongside a J.D. from Seattle University School of Law. The firm reports roughly 500 patent and trademark applications prosecuted, about 3,000 applications examined during his USPTO tenure, and more than 18 years of patent, trademark, and copyright experience.

The practice covers utility and design patents, trademark applications and registration, and related disputes including opposition, infringement, and litigation. Technical work spans consumer products, software and AI systems, mobile applications, nutrition and chemical formulations, mechanical devices, and electrical and biomedical systems. Clients include individual inventors filing a first application, startups building a brand around a new product or app, and businesses managing larger portfolios. Filings are handled before the USPTO, with bar admissions listed for Texas state courts and the Eastern, Southern, and Northern Districts of Texas.

What reviewers return to most is responsiveness and follow-through. Clients describe prompt replies, proactive updates, and clear explanations of where a matter stands during a process that can stretch over months. Several mention results that other attorneys had called unlikely, including issued patents on products initially deemed unpatentable, and one describes examiner interviews used to overcome rejections. Billing draws repeated comment as well, with reviewers noting fair pricing and an absence of hidden or unexpected charges. Communication style is frequently characterized as patient and educational, which matters to first-time applicants unfamiliar with prosecution.

Patent prosecution is not a straight line: one reviewer’s design patent drew a conditional rejection that required amendments before approval, and appeals and examiner interviews are part of the described workflow. Timelines are long by nature, particularly for trademarks. Some clients also arrive with filings left in disarray by prior counsel, which must be corrected before a case can move forward.

Prosecution is rarely a single-step process; one client’s design patent received a conditional rejection that required amendments before approval, and appeals and examiner interviews form part of the described workflow. Patent and trademark timelines run long, and reviewers note that the trademark process in particular takes considerable time to complete. Some clients arrive with applications mishandled by previous counsel, meaning cleanup work can be required before a case can move forward.
