When protecting your invention matters most, you need a patent attorney with both legal expertise and technical depth. mjIP, headquartered in Irvine, California, is led by Mandana Jafarinejad, Esq. — a USPTO-registered patent attorney with a B.S. in Biology from Cal Poly Pomona and over 15 years of intellectual property experience. After working in-house at a Fortune 500 pharmaceutical company in Orange County, Attorney Jafarinejad founded mjIP in 2010 to give inventors and businesses in Southern California access to the same level of IP sophistication that large corporations command.

mjIP specializes in patent law for the life sciences, biotech, pharmaceutical, and supplement industries — areas where the science is complex, the competition is fierce, and patent protection is absolutely critical to business success. Whether you are a solo inventor, a biotech startup, or an established pharmaceutical company, our Irvine patent attorney delivers the strategic, technically informed patent representation you need.

Patent prosecution is the process of preparing and filing a patent application with the United States Patent and Trademark Office (USPTO) and navigating the examination process until your patent is granted. It requires both legal precision and technical expertise — especially for complex inventions in biotech, pharma, and supplement science. mjIP handles every step of the patent prosecution process:

Prior art search to determine patentability of your invention. Drafting strong, strategically written patent claims that maximize the scope of your protection. Filing provisional and non-provisional utility patent applications. Responding to USPTO office actions with technical arguments that advance your application. Prosecuting continuation and divisional applications to expand your patent portfolio.

Attorney Jafarinejad's background in the pharmaceutical industry gives clients in the life sciences sector a critical edge: she understands the science behind your invention at a depth that most patent attorneys cannot match. That technical fluency translates directly into stronger patent claims, better arguments before the USPTO, and ultimately more valuable patent rights for our clients across Orange County, San Diego, and the Bay Area.

The biotech, pharmaceutical, and supplement industries represent some of the most intellectually rich — and legally complex — patent landscapes in the world. A single formulation, process, or molecular compound can be worth millions in protected market exclusivity. Getting the patent right from the beginning is not optional — it's essential.

mjIP has extensive experience helping clients in these verticals secure meaningful patent protection:

Biotech patents: recombinant DNA technology, gene editing methods, cell-based therapies, diagnostic assays, bioreactor processes, and novel biological compounds. Pharmaceutical patents: drug formulations, dosage forms, delivery mechanisms, synthesis routes, metabolites, and methods of treatment. Supplement patents: novel nutraceutical formulations, proprietary blends, bioavailability enhancement methods, and extraction processes.

For biotech, pharmaceutical, and supplement companies in Orange County, San Diego, and Los Angeles, mjIP provides patent prosecution and portfolio management that aligns intellectual property strategy with business goals. Our deep industry knowledge means we can identify patentable innovations that less specialized firms might overlook — and draft claims that stand up under examination and litigation.

When patent rights are infringed — or when you receive an infringement allegation — decisive legal action is required. mjIP represents clients in patent litigation matters, providing both offensive enforcement and defensive representation. Whether you need to stop a competitor from copying your patented technology or defend yourself against a patent infringement claim, our Irvine patent attorney delivers experienced, technically grounded litigation strategy.

Patent litigation in the pharmaceutical, biotech, and supplement space is particularly technical. Courts and opposing counsel must grapple with complex scientific questions about claim construction, infringement analysis, and validity challenges. Attorney Jafarinejad's scientific training and pharmaceutical industry background position mjIP clients for success in these demanding proceedings.

In addition to utility patents, mjIP handles design patent applications for clients in Orange County and across Southern California. Design patents protect the ornamental appearance of a product — its unique visual design — for a period of 15 years. For supplement brands, consumer product companies, and medical device manufacturers whose product appearance drives purchase decisions, a design patent can be an essential component of a comprehensive IP strategy.
