In 2013, Flextronics launched Lab IX, an accelerator program based out of Milpitas (where the company also has an R&D centre), 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 centre 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.^[23]

In 2015, the company rebranded itself as a “Sketch-to-Scale” solutions provider. The term, “Sketch-to-Scale”, is a registered trademark of Flex. Flex provides its 2,500 designer engineers to prospective customers. In this program, Flex will help develop the customer's product from an idea (or “sketch”) to manufactured product (“scale”). These customers can send their own design engineers to Flex’s innovation lab, an ultra-secure work area where customers can pursue top-secret projects, to understand how to develop concepts into products.^[24] Flex targets small start-up companies for this service and promises confidentiality. These companies will then have access to Flex’s team of experienced designers and manufacturers. The program is advertised to take a product through several stages of production, including concept design, prototype creation, improving the supply chain distribution and logistics, and globalization.^[25]

Flextronics was sued what was apparent in breach of contract with Beckman Coulter Inc., a global leader in medical device solutions. 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 analyser. 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.

Beckman filed suit in early 2001, seeking $2.2 million in damages, which were cited as the costs incurred in having to retool one of its plants to manufacture the circuit boards in-house.^[26][27] At the end of the trial, Flextronics paid $23 million for the damages.^[28]

A former Flextronics executive pleaded guilty to committing wire fraud and security fraud by providing confidential information related to USB charger shipment data used for U.S. based iPhones and iPods for the third and fourth quarters of 2009.^[29]
