New varieties of oysters that have become an important part of the global aquaculture industry have earned Rutgers researcher Ximing Guo a 2026 Edison Patent Award from the Research & Development Council of New Jersey (RDNJ). Guo’s invention is one of two Rutgers innovations recognized this year with the state’s highest honor for inventors and innovation.

Guo, Distinguished Professor in the Department of Marine and Coastal Sciences, received the Aquaculture Award for his patent, Molluscan Shellfish Produced by Controlled Crossbreeding (U.S. Patent No. 11,266,131). Conducting research at the Haskin Shellfish Research Laboratory, Guo has developed new oyster varieties for aquaculture in the Mid-Atlantic and Northeastern United States with improved disease resistance, growth, and genetic diversity. The resulting oysters are more uniform, faster growing, healthier, and better suited to commercial production.

“It is deeply rewarding to see the breeding technologies developed at Rutgers contributing to oyster farming across the U.S. and around the world,” said Guo. “Oysters are remarkable organisms, valued not only as a premium seafood but also for the essential ecological services they provide. They face many diseases, and disease resistance is the single most important trait for oyster aquaculture and is critical for the restoration of natural populations devastated by disease. I remain grateful to the many students and colleagues whose dedication and expertise have shaped our breeding program over the years.”

Guo’s patented breeding technology has helped advance oyster farming both in the United States and internationally by addressing disease resistance, one of the industry’s greatest challenges, while improving productivity and supporting the restoration of natural oyster populations.

Also receiving a 2026 Edison Patent Award is a Rutgers School of Engineering research team for developing structural plastic lumber made from recycled plastics, including milk containers, coffee cups, and plastic bottles. The durable material has been used to manufacture approximately 1.5 million railway ties in the United States, diverting an estimated 300 million pounds of plastic from landfills and oceans.

This marks the fifth consecutive year that two Rutgers research teams have received Edison Patent Awards. The Rutgers researchers will be honored alongside this year’s other recipients during the RDNJ awards ceremony and banquet in November.

Now in its 47th year, the Edison Patent Awards recognize outstanding patented innovations developed in New Jersey across 12 categories. Named for Thomas Edison, the awards celebrate research that demonstrates significant scientific achievement, originality, commercial impact, and societal benefit.

R&D Council board members selected the winners after evaluating nominated patents for the significance of the problem addressed, utility and socioeconomic value, novelty, and commercial impact. At least part of the scientific or technical work supporting each winning patent must have been completed in New Jersey.

The Rutgers Office for Research supported both award-winning teams through its Technology Transfer unit, assisting with patent protection, licensing, and nominations for the 2026 Edison Patent Awards. To learn more about the Rutgers technology transfer process, visit innovate.rutgers.edu.
