In August 2016, the state of Massachusetts and the city of Boston offered the company more than $3 million in public aid to entice the company to open its Flex Boston Innovation Center on the South Boston waterfront. The 17,000 square feet (1,600 m 2 ) facility will employ 25 people and be located in a former military storehouse in the Seaport, now called the Innovation and Design Building. 
In 2013, Flextronics launched Lab IX, an accelerator program based out of Milpitas (where the company also has an R&D center), which will award $500,000 to each selected company to grow their ideas and bring it to market.
The focus of Lab IX is to find start-ups that are less than three years old, have less than $5 million in funding — “early stage disruptive companies incorporating hardware and software innovation”. In addition to a capital injection, Lab IX will also provide access to Lab IX and Flextronics’ engineers and designers, including IDEO, access to manufacturing and prototyping equipment — some $30 million in the R&D center alone. Those who look like they may be progressing to the next stage of their development get access to Flextronics’ network of factories for manufacturing, procurement network and marketing network. 
Breach of contracts
Flextronics was sued what was apparent in breach of contract with Beckman Coulter Inc., a medical device maker. The case dates from 1997, when Beckman Coulter entered into an agreement with Dovatron, a unit of the Dii Group, to provide circuit boards for a Beckman blood analyzer. Flextronics acquired the Dii Group in 1999 and, according to Beckman, shortly thereafter Flextronics refused to provide the circuit boards unless it bought other electronic components from the company.
At the end of trial, Flextronics paid $23 million for the damages.
