I'll research Atmel Corporation to verify its profile.
Atmel Corporation — commonly "Atmel" — was an American semiconductor designer and manufacturer founded in 1984 by George Perlegos, headquartered at 1600 Technology Drive, San Jose, California. It traded on NASDAQ under the ticker ATML and reported roughly 5,100 employees and about $1.8 billion in FY2011 revenue (Wikipedia/SEC filings). It is no longer independent: Microchip Technology agreed to acquire Atmel in January 2016 in a cash-and-stock deal valued at roughly $3.56–3.6 billion, closing in April 2016 after Atmel terminated a prior agreement with Dialog Semiconductor (paying a $137.3 million break fee). Atmel is now a wholly owned Microchip subsidiary; its stock was delisted.
Products and operations. Atmel was an operating semiconductor company, not a licensor. Its largest line was microcontrollers: 8-bit and 32-bit AVR, ARM-based (AT91/SAM) devices, and improved 8051 derivatives, supported by the free Atmel Studio IDE. Other lines included RF/wireless chips (Wi-Fi from the Ozmo and Newport Media acquisitions, Zigbee modules, ISM-band transceivers, RFID), capacitive touch controllers and the XSense flexible touch sensor line, memory (serial/parallel EEPROM, flash, EPROM, CryptoMemory), hardware security and authentication parts (CryptoAuthentication, CryptoRF, TPM), sensor hubs, LED drivers, and automotive-qualified and smart-metering ICs. It pursued a "fab-lite" strategy, having divested fabs in France, Germany and the UK while retaining a Colorado Springs facility for XSense.
Patent-litigation posture. The tracked data show a single case, and Atmel appears only as a defendant — the classic profile of an operating company targeted by an assertion entity rather than an NPE asserting an acquired portfolio. It filed no plaintiff-side suits in this database.
Notable case. Azure Networks LLC et al. v. Texas Instruments Incorporated et al. (filed Dec. 22, 2010, E.D. Tex., Tyler Division) named Atmel as one of multiple defendants, alongside Texas Instruments. The venue is the Eastern District of Texas, a historically plaintiff-friendly district frequently used by patent-assertion entities. The case reflects Atmel's exposure as a microcontroller and wireless-chip supplier rather than any assertion activity of its own.
