TESSERA TECHNOLOGIES ANNOUNCES FOURTH QUARTER 2009 RESULTS

San Jose, Calif., Jan. 28, 2010 –Tessera Technologies, Inc. (Nasdaq: TSRA) announced its results for the fourth quarter ended Dec. 31, 2009.

Revenue Highlights: Fourth Quarter 2009

• Total revenues were $56.5 million.

• Micro-electronics revenue was $48.5 million.

• Imaging & Optics revenue was $8.0 million.

Fourth quarter 2009 Micro-electronics revenue was comprised entirely of Royalties and License Fees. Micro-electronics did not have Products and Services revenue, due to the company’s previously announced decision to no longer pursue government funded Research and Development contracts that had been the source of this revenue. Imaging & Optics revenue was comprised of $3.3 million in Royalties and License Fees, and $4.7 million in Products and Services.

Generally accepted accounting principles (GAAP) net income for the fourth quarter of 2009 was $6.4 million, or $0.13 per diluted share, which included non-cash charges of $7.5 million for stock-based compensation and $3.3 million for amortization of acquired intangibles.

Non-GAAP net income for the fourth quarter of 2009 was $16.0 million or $0.31 per diluted share. Non-GAAP net income is defined as income and operating expenses adjusted for acquired intangibles amortization, charges for acquired in-process research and development, stock-based compensation expense, and related tax effects.

“Micro-electronics Royalties and License Fees of $48.5 million in the fourth quarter of 2009 drove our full year 2009 Micro-electronics Royalties and License Fees to $269.7 million. We generated $29.7 million in Imaging & Optics revenue in 2009, which resulted in $299.4 million in total revenues,” said Henry R. Nothhaft, chairman and chief executive officer, Tessera. “We signed six new licensees in 2009, two in Micro-electronics and four in Imaging & Optics. This expanded customer base is one key growth driver for us in 2010. Our growth will also come from the expected recovery in our served markets - DRAM, Wireless, Semiconductor Capital Equipment, and Consumer Optics.”

Revenue Highlights: Full Year 2009

• Total revenue was $299.4 million.

• Micro-electronics revenue was $269.7 million.

• Imaging & Optics revenue was $29.7 million.

Micro-electronics revenue for the full year ended Dec. 31, 2009 was comprised of $269.7 million in Royalties and License Fees, and $48,000 in Products and Services. Imaging & Optics revenue for the full year ended Dec. 31, 2009 was comprised of $16.5 million in Royalties and License Fees, and $13.2 million in Products and Services.

GAAP net income for the full year was $69.8 million, or $1.42 per diluted share. Non-GAAP net income for the full year was $101.5 million, or $2.02 per diluted share.

First Quarter 2010 Financial Guidance

First quarter 2010 total revenues are expected to range between $58.0 million and $61.0 million. This compares to the company’s previous guidance, given on January 6, 2010, of between $59.0 million and $61.0 million. The new guidance is due the company’s assessment of recent public announcements from certain of the company’s licensees. This compares to first quarter 2009 total revenues of $114.6 million. Excluding $60.6 million from Amkor related to the resolution of the companies’ arbitration, first quarter 2009 total revenues were $54.0 million.

First quarter 2010 Micro-electronics revenue is expected to range between $50.0 million and $53.0 million, all of which will be royalty and license related. This compares to the company’s previous guidance, given on January 6, 2010, of between $51.0 million and $53.0 million. Tessera has two major DRAM customers with volume-based pricing incentives. These pricing incentives will have an impact on the company’s revenue in the first quarter of 2010 similar to their impact on the company’s revenue in the fourth quarter of 2009. As a reminder, Tessera recognizes royalty revenue one quarter in arrears.

As a comparison, in the first quarter of 2009, Micro-electronics Royalties and License Fees revenue was $106.5 million and included the $60.6 million payment by Amkor. Without the Amkor payment, Micro-electronics Royalties and License Fees were approximately $45.9 million.

2

First quarter 2010 Imaging & Optics revenue, in total, is expected to be approximately $8.0 million. Imaging & Optics Royalties and License Fees revenue is expected to be approximately $4.0 million. Imaging & Optics Products and Services revenue is expected to be approximately $4.0 million. This compares to Imaging & Optics Royalties and License Fees revenue of $5.3 million and Products and Services revenue of $2.7 million in the first quarter of 2009, which totaled $8.0 million for this segment. First quarter 2009 Imaging & Optics Royalties and License Fees revenue included approximately $3.6 million in license fees.

Non-GAAP operating expenses for the first quarter of 2010 are projected to range between $32.0 million and $33.0 million, excluding litigation expenses.

Litigation Update

On Jan. 28, 2010, Tessera filed its Notice of Appeal in Investigation No. 337-TA-630 (DRAM ITC action). This initiated the company’s appeal in the Court of Appeals for the Federal Circuit.

Management believes that the non-GAAP measures used in this report provide investors with important perspectives into the company’s ongoing business performance.

The non-GAAP financial measures used by the company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.
