Jennifer Doudna

At Berkeley, Doudna’s lab explored many facets of RNA biology, including ribozymes, ribonucleoprotein complexes, and mechanisms of RNA‑mediated regulation.[6][12] Her expertise in structural biology positioned her to investigate complex RNA–protein systems such as CRISPR, which would later become central to her career. Colleagues and biographical accounts emphasize that her longstanding focus on RNA’s structural and functional diversity laid the groundwork for her contributions to genome editing.[6][12][15]

Co‑Discovery and Development of CRISPR-Cas9 Genome Editing

Doudna is best known for her pioneering work on CRISPR‑Cas9 genome editing. CRISPR (clustered regularly interspaced short palindromic repeats) refers to segments of bacterial DNA that store fragments of viral genomes, while Cas proteins are enzymes that use CRISPR‑derived RNA guides to recognize and cut foreign DNA.[14] By the early 2010s, microbiologists had begun to elucidate CRISPR systems as adaptive immune mechanisms in bacteria, but their potential as programmable genome‑editing tools was not yet realized.

Through collaborations, most notably with French microbiologist Emmanuelle Charpentier, Doudna’s group investigated how CRISPR‑associated RNAs and the Cas9 protein function at the molecular level.[4][10][14] In a seminal 2012 paper, they showed that a simplified, dual‑RNA guided Cas9 system could be reprogrammed to cut DNA at chosen sequences in vitro, effectively turning bacterial defense machinery into a versatile "genetic scissors" technology.[14] This work demonstrated that CRISPR‑Cas9 could be engineered for high‑precision genome editing.

Building on this conceptual breakthrough, Doudna and co‑inventors at UC Berkeley and the University of Vienna filed a broad patent application covering CRISPR‑Cas9 gene editing in all environments—bacteria, plants, animals, and human cells—on 25 May 2012, as documented in UC Berkeley’s CRISPR timeline.[0] This first‑to‑file event marked the start of a complex patent landscape involving multiple institutions and companies.

In subsequent years, laboratories around the world rapidly adopted CRISPR‑Cas9 as a standard tool for editing genomes, studying gene function, creating disease models, and exploring new therapeutic approaches.[10][14] Doudna’s research continued to refine CRISPR systems, improve specificity, and explore variants such as base editors and prime editors, although many of these innovations also involved other scientists. Her role remained central in establishing CRISPR‑Cas platforms as robust, programmable technologies.

Patent Landscape and Intellectual Property Milestones

The emergence of CRISPR‑Cas9 led to an intense competition over intellectual property. While Doudna’s consortium filed early, the Broad Institute pursued expedited examination and on 15 April 2014 received the first U.S. CRISPR‑Cas9 patent, primarily covering applications in eukaryotic cells.[1][2] Analyses in Nature Biotechnology and other venues discuss how this grant sparked patent interference proceedings between the Broad and the University of California over priority and scope.[1][2]

In Europe, the European Patent Office granted the UC Berkeley–University of Vienna team the first CRISPR‑Cas9 patent in the European Union on 10 May 2017, covering uses in plants, animals, and human cells.[0] This milestone secured key intellectual property for Doudna’s inventions across the EU.

In the United States, the U.S. Patent and Trademark Office (USPTO) granted U.S. Patent No. 10,000,772 to the UC team on 19 June 2018, recognized by UC Berkeley as their first U.S. CRISPR‑Cas9 patent grant.[0] A joint press release from CRISPR Therapeutics, Intellia Therapeutics, and Caribou Biosciences highlighted the patent’s importance for genome‑editing applications.[3] Subsequent grants on 28 May 2019 (U.S. Patent 10,301,651, covering CRISPR methods for sequence‑specific gene repression and activation) and 2 July 2019 (U.S. Patent 10,337,029, covering methods of cleaving and modifying DNA using CRISPR complexes) expanded the UC portfolio.[0]

On 1 October 2019, the USPTO granted U.S. Patent No. 10,428,352 to the UC team, prompting Berkeley News to report that the university then held the largest CRISPR‑Cas9 patent portfolio in the United States.[0] These milestones underscored Doudna’s dual role as scientific innovator and central figure in the legal and commercial frameworks surrounding genome editing.
