Patent Attorney in Irvine, CA
mjIP is a patent law firm in Irvine, CA, led by USPTO-registered patent attorney Mandana Jafarinejad, Esq. The firm handles patent prosecution, application drafting, and patent litigation for inventors and companies across Orange County, San Diego, and the Bay Area, with concentrated experience in the life sciences. With 15+ years of IP experience and a background in pharmaceutical R&D, mjIP delivers technically grounded representation.
A Patent Attorney Who Knows the Science
Protecting an invention takes both legal skill and technical understanding. Attorney Jafarinejad holds a B.S. in Biology and worked in-house as a patent attorney and research scientist at a Fortune 500 pharmaceutical company before founding mjIP in 2010. That combination allows the firm to understand the science and translate it into strong, defensible claims for clients across Southern California.
Patent Prosecution in Irvine, CA
Patent prosecution is the process of preparing and filing an application with the USPTO and advancing it through examination to grant. It requires precision — especially for biotech, pharma, and supplement inventions. mjIP handles each step:
- Prior-art search to assess patentability
- Drafting strategically written claims that maximize protection
- Filing provisional and non-provisional utility applications
- Responding to USPTO office actions with technical arguments
- Prosecuting continuations and divisionals to expand a portfolio

Common Questions
Frequently Asked Questions
Utility patents are enforceable for 20 years from the earliest non-provisional filing date, subject to maintenance fees. Design patents granted after May 13, 2015 last 15 years from grant.
Any new, useful, and non-obvious process, machine, manufacture, or composition of matter — including drug formulations, biotech processes, supplement compounds, and devices. Design patents protect a product’s ornamental appearance.
The USPTO allows self-filing for individuals, but claim drafting is a highly technical skill and weak claims are easy to design around or invalidate. Working with a USPTO-registered attorney improves the odds of a broad, enforceable patent.
