Brown and a small group of early employees tested the hunch by digging up clover roots, which for the plant kingdom contain high amounts of heme. "I dissected them off with a razor blade then blended them up just to see what I could extract. I was just poking around, feasibility-testing some ideas. I got to a point where, though I didn’t have much data, I had enough to go and talk to some venture-capital companies — of which there are a ridiculous number in Silicon Valley — and hit them for some money,” Brown told The Sunday Times. Brown raised a Series A round of $9 million from Khosla Ventures and founded Impossible Foods in July 2011. Brown and his team spent five years researching and developing the Impossible Burger, which launched in restaurants in 2016. Impossible Foods is also working on plant-based pork, chicken, fish and dairy products made without any animals.

Brown strongly supports labeling Impossible Foods’ products as “meat,” regardless of its source. In a 2018 interview with Quartz, he noted, “animals have just been the technology we have used up until now to produce meat... What consumers value about meat has nothing to do with how it’s made. They just live with the fact that it’s made from animals. If we’re producing a product that is delivering everything that is of value in meat for consumers, it’s filling that niche.” This assessment, according to Brown, appropriately categorizes meat by “what functional role it plays,” rather than its source of origin. These statements have put Brown at odds with the meat industry, which by mid-2019 had successfully pressured state legislatures in Missouri and Arkansas to pass laws barring plant-based protein manufacturers such as Impossible Foods and competitor Beyond Meat from labeling their products as “meat.”

In 2016, the Geneva, Switzerland-based World Economic Forum named Brown a Technology Pioneer for his design, development and deployment of new technologies and innovations "poised to have a significant impact on business and society."

In 2010 the Association of Biomolecular Resource Facilities (ABRF) selected Brown for the ABRF 2010 Award in recognition of Brown's pioneering work in the development of microarrays and the diverse applications of this technology in genetic research.

In 2009, Brown took an 18-month sabbatical where he considered how to spend the rest of his career. Brown decided that the world's largest environmental problem, and the problem where he could have the most impact, was the use of animals to produce food. He organized a conference to raise awareness of the problem. But the National Research Council workshop, called "The Role of Animal Agriculture in a Sustainable 21st Century Global Food System,” had minimal impact; soon after, he decided the best way to reduce animal agriculture was to offer a competing product in the free market.

In 2006 he received the American Cancer Society's Medal of Honor for Basic Research, acknowledging "his revolutionary development of low-cost, accessible automated microarrays, and his life-saving contributions to the field of functional genomics...which in turn has produced insights into critical genetic information for diseases such as leukemia, lymphoma, prostate cancer, and early stage breast cancer."

In 2005 he received the Curt Stern Award for his contributions to the development and application of gene-based expression microarrays.

In 2002, Brown was elected to the United States National Academy of Sciences, identifying him as one of the top 2000 scientists in the nation. He is a member of the National Academy of Medicine and a Fellow of the American Association for the Advancement of Science.

In 2002 he received a Takeda award, recognizing his work in "the development of DNA microarrays with pre-synthesized DNA probes and the promotion of the technology by releasing the production methods on the Internet."

In 2001, Brown, Eisen and Varmus co-founded the Public Library of Science (PLOS) to make published scientific research open access and freely available to researchers in the scientific community. Funded by a grant from the Gordon and Betty Moore Foundation, the non-profit organization advocated for designing alternative systems to fund for scientific publishing.

In 2000, Brown received the National Academy of Sciences Award in Molecular Biology.

Starting in the late 1990s, Brown began publicly voicing concern over what he called "a fundamentally flawed process of scientific publishing," in which academics typically published results of publicly funded research in private, commercial publishing houses that charged subscription fees for access to journals. “We viewed this entire process as being patently unfair. Not only were scientists in poor countries being denied access to the latest and best information out there, but the public who supports this research was being denied access as well. We felt there simply had to be a better way to do it," Brown told a University of Chicago medical journal.

In 1988, Brown became an investigator of the Howard Hughes Medical Institute and an assistant professor in the Department of Biochemistry at Stanford University School of Medicine, where he continued to investigate retroviral replication. In the early 1990s, Brown began developing a new technology to enable systematic investigation of the behavior and properties of whole genomes—called DNA microarrays. "I had a mental image of a DNA microarray, even including the red and green fluorescent spots, a few years before I'd figured out the details of making them," Brown told The Scientist.

After getting his medical degree in 1982, Brown completed a 3-year pediatric residency at Children's Memorial Hospital in Chicago but decided he could have a greater impact through basic research. In 1985, Brown took a 3-year postdoctoral fellowship at University of California, San Francisco with J. Michael Bishop and Harold Varmus (who shared the 1989 Nobel Prize in Medicine for their discoveries about how genes can ignite cancerous tumors). At UCSF, Brown and colleagues defined the mechanism by which retroviruses, such as the AIDS virus, integrate their genes into the genome of the cells they infect, which helped lead to development of new drugs to fight the disease.

Brown received each of his degrees from the University of Chicago, including his B.S. in 1976 and M.D. in 1982. His Ph.D., granted in 1980 while under the guidance of Nicholas R. Cozzarelli, involved the study of DNA topoisomerases.

Patrick "Pat" O'Reilly Brown (born 1954) is chief executive and founder of Impossible Foods Inc. and professor emeritus in the department of biochemistry at Stanford University. Brown is co-founder of the Public Library of Science, inventor of the DNA microarray, and a former investigator at Howard Hughes Medical Institute.
