51�ԹϺ���

SAN FRANCISCO — A federal jury has ruled in favor of the University of California in its lawsuit with two former 51�ԹϺ��� Davis strawberry breeders and the private breeding company they created with 51�ԹϺ���-owned plants. A separate jury is expected to decide issues related to damages at a later time.

The jurors unanimously decided that Douglas Shaw and Kirk Larson willfully infringed 51�ԹϺ��� patents, breached duties of loyalty and fiduciary duty and used plant material owned by the 51�ԹϺ��� Davis Public Strawberry Breeding Program to develop berries for California Berry Cultivars, or CBC, a corporate breeding firm they established along with several large commercial nurseries and growers.

“This federal jury decision is good news for public strawberry breeding at 51�ԹϺ��� Davis and all strawberry farmers throughout California and the world,” said Helene Dillard, dean of the 51�ԹϺ��� Davis College of Agricultural and Environmental Sciences. “Our revitalized public strawberry breeding program will continue to develop affordable, high-quality varieties and train the next generation of breeders to serve every strawberry farmer, shipper, processor, and consumer.”

During the five-day trial, the jury heard evidence that Larson and Shaw — while still employed by the university — used both patented and unpatented strawberry breeding stock developed by generations of 51�ԹϺ��� strawberry breeders to make crosses in Spain for their private company. Evidence showed they harvested the seeds from those 51�ԹϺ��� varieties and unreleased plant material and sent them back to California to produce pedigree plants without the university’s knowledge or permission. 

Shaw and Larson retired from the 51�ԹϺ��� Davis Public Strawberry Breeding Program in 2014 after decades of successful breeding for the university, working with plant material they inherited from university breeders before them. Shaw and Larson sought a license from the university to use the 51�ԹϺ��� varieties in their new business. The university ultimately decided not to grant a license to Shaw and Larson, but the evidence showed that Shaw, Larson and CBC decided to use university varieties and germplasm anyway.

Shaw, Larson and CBC filed a lawsuit against the University of California, charging the university with “breach of contract, conversion, breach of fiduciary duty, breach of implied covenant of good faith and fair dealing, and unfair competition” by attempting to patent the material rather than license it to CBC.

In a summary judgment decision issued in early May, District Judge Vince Chhabria threw out all but the claim of breach of good faith for the university’s decision to patent the plants. The jury ruled against that one CBC claim.

Especially important was testimony from Stephen Dellaporta, an expert in plant genetics at Yale University, who conducted DNA analysis for CBC plants grown in California from seeds imported from Spain.

“Ninety-nine percent of the genetic diversity of 51�ԹϺ��� Davis patented varieties was captured by CBC’s breeding activity,” said Dellaporta, professor of molecular, cellular and developmental biology at Yale. “Also, CBC’s seedlings contain genetic material from five university-patented varieties that had not been released at the time they were bred, and 19 that had never been released.”

California a leading strawberry producer

California is a leading producer of both fresh and processed strawberries, providing more than 87 percent of the strawberries consumed in North America. Strawberry varieties developed at 51�ԹϺ��� Davis produce about 60 percent of the strawberries consumed worldwide and generate $2.5 billion a year.

California growers pay lower rates than other farmers for strawberries developed by the 51�ԹϺ��� Davis Public Strawberry Breeding Program and get access to new varieties before growers elsewhere. Fees from licensing strawberry varieties go back to the program to support the research, training and innovation on which the industry relies.

“We appreciate the great varieties the university has produced over the years, and we look to what the future holds,” said Neil Nagata, a third-generation strawberry grower from San Diego County.

Professor Steve Knapp took over the 51�ԹϺ��� Davis Public Strawberry Breeding Program in February 2015 and has several new varieties in the works, focusing on improved strawberry yield, flavor, shelf life, production efficiency and disease resistance.

The case is scheduled to return to court next Wednesday, May 31, when the judge will consider remedies that were not for the jury to decide.
