segment information is not separately 31 discussed below as the operating results for nbg did not meet the quantitative thresholds for segment reporting in 2010. for additional information concerning segment reporting , see note 13 , business segments and major customers ,  of notes to consolidated financial statements of this form 10-k. the key elements of our strategy are as follows : innovate : develop and patent our innovative technology to provide fundamental competitive advantage when incorporated into semiconductors , and digital electronics products and systems . drive adoption : communicate the advantages of our patented innovations and technologies to the industry and encourage its adoption through demonstrations and incorporation in the products of select customers . monetize : license our patented inventions and technology solutions to customers for use in their semiconductor and system products . as of december 31 , 2010 , our semiconductor , chip interface , lighting , display and other technologies are covered by approximately 1,180 u.s. and foreign patents . additionally , we have approximately 850 patent applications pending . these patents and patent applications cover important inventions in memory and logic chip interfaces , optoelectronics , mobile applications and other technologies . some of the patents and pending patent applications are derived from a common parent patent application or are foreign counterpart patent applications . we have a program to file applications for and obtain patents in the united states and in selected foreign countries where we believe filing for such protection is appropriate and would further our overall strategy and objectives . in some instances , obtaining appropriate levels of protection may involve prosecuting continuation and counterpart patent applications based on a common parent application . we believe that our patented innovations provide our customers means to achieve higher performance , improved power efficiency , lower risk , and greater cost-effectiveness in their digital electronics products and systems . our patented innovations and technologies are offered to our customers through either a patent license or a technology license . our revenues are primarily derived from patent licenses , through which we provide a license to our broad portfolio of patented innovations primarily to semiconductor and system companies who use these innovations in the development and manufacture of their own products . our patent licensing agreements may provide a license to all or part of our patent portfolio for a particular use , product or technology . the patent license essentially provides our customers with a defined right to use our patented innovations in the customer 's own digital electronics products and systems . patent license agreements are generally structured with variable royalty payments , although some agreements include fixed payments over certain defined periods . we also offer our customers technology licenses . we typically offer technology licenses to support the implementation and adoption of our patented innovations and technologies through know-how and technology transfers , product design , development , and system integration consulting and engineering services . our technology license offerings also include a range of solutions developed by rambus , which include leadership solutions ( which are rambus-proprietary solutions widely licensed to our customers ) and industry-standard solutions that we provide to our customers under license for incorporation into our customers ' digital electronics products and systems . due to the often complex nature of implementing state-of-the art technology , we also offer engineering services to our customers to help them successfully integrate our solutions into their digital electronics products and systems . these technology license agreements may have both a fixed price ( non-recurring ) component and ongoing royalties . engineering services are generally offered on a fixed price basis . further , under technology licenses , our customers typically receive licenses to our patents necessary to implement these solutions in their products with specific rights and restrictions to the applicable patents elaborated in their individual contracts with us . royalties represent a substantial majority of our total revenue . we derive the majority of our royalty revenue by licensing our broad portfolio of patents for chip interfaces to our customers . such licenses may cover part or all of our patent portfolio . leading semiconductor and system companies such as amd , fujitsu , intel , panasonic and samsung have licensed our patents for use in their own products . we also derive additional revenue by licensing a range of technology solutions including our leadership architectures and industry-standard solutions to customers for use in their semiconductor and system products . our 32 customers include leading companies such as elpida , ibm , panasonic , samsung , sony and toshiba . due to the complex nature of implementing our technologies , we provide engineering services under certain of these licenses to help our customers successfully integrate our technology solutions into their semiconductors and system products . licensees also may receive , in addition to their technology license agreements , patent licenses as necessary to implement the technology in their products with specific rights and restrictions to the applicable patents elaborated in their individual contracts . the remainder of our revenue is contract services revenue which includes license fees and engineering services fees . the timing and amounts invoiced to customers can vary significantly depending on specific contract terms and can therefore have a significant impact on deferred revenue or account receivables in any given period . we intend to continue making significant expenditures associated with engineering , marketing , general and administration including litigation expenses , and expect that these costs and expenses will continue to be a significant percentage of revenue in future periods . whether such expenses increase or decrease as a percentage of revenue will be substantially dependent upon the rate at which our revenue or expenses change . story_separator_special_tag for the year ended december 31 , 2009 as compared to the same period in 2008 , total engineering costs decreased primarily due to lower headcount and the related decrease in salary , benefits , allocations and stock based compensation expenses as well as decreases in consulting and travel and entertainment costs as a result of our cost reduction initiatives that commenced in the second half of 2008. in the near term , we expect engineering costs to be lower than in 2010 as the employee bonus related to the samsung settlement was a one-time event in 2010. however , we intend to continue to make investments in the infrastructure and technologies required to maintain our product innovation in semiconductor and lighting technologies and , as a result , our headcount and infrastructure costs are expected to increase . marketing , general and administrative costs : replace_table_token_6_th 38 marketing , general and administrative expenses include expenses and costs associated with trade shows , public relations , advertising , litigation , general legal , insurance and other marketing and administrative efforts . litigation expenses are a significant portion of our marketing , general and administrative expenses and can vary significantly from quarter to quarter . consistent with our business model , our licensing and marketing activities aim to develop or strengthen relationships with potential and current licensees . in addition , we work with current licensees through marketing , sales and technical efforts to drive adoption of their products , that use our innovations and solutions , by system companies . due to the long business development cycles we face and the semi-fixed nature of marketing , general and administrative expenses in a given period , these expenses generally do not correlate to the level of revenue in that period or in recent or future periods . for the year ended december 31 , 2010 as compared to 2009 , total marketing , general and administrative costs decreased primarily due to lower litigation expenses . non-litigation related marketing , general and administrative costs increased for the year ended december 31 , 2010 primarily due to funding for our 2010 cip , which includes the employee bonus related to the samsung settlement , increased consulting fees , increased general legal expenses and increased headcount in corporate development commencing in 2009 as a result of our strategic initiatives to identify and acquire additional technology opportunities . for the year ended december 31 , 2009 as compared to 2008 , total marketing , general and administrative costs were higher due primarily to ongoing patent acquisition activities in 2009 , higher headcount in corporate development as a result of our strategic initiatives related to our investing activities , increased stock-based compensation expenses primarily related to nonvested equity awards granted during late 2008 and early 2009 , and higher allocated costs . these increases were offset by decreases in depreciation expenses , rent and facilities expenses and overall marketing expenses due primarily to our cost reduction initiatives taken in 2008. litigation expenses remained relatively flat from 2008 to 2009 as we continued to pursue litigation against those companies that have infringed on our patented technologies . in the future , marketing , general and administrative costs will vary from period to period based on the trade shows , advertising , legal , acquisition and other marketing and administrative activities undertaken , and the change in sales , marketing and administrative headcount in any given period . litigation expenses are expected to vary from period to period due to the variability of litigation activities . costs ( recoveries ) of restatement and related legal activities , net : replace_table_token_7_th * nm  percentage is not meaningful as the change is too large costs ( recoveries ) of restatement and related legal activities , net , consist primarily of investigation , audit , legal and other professional fees related to the 2006-2007 stock option investigation and the filing of the restated financial statements and related litigation . for the year ended december 31 , 2010 , costs of restatement and related legal activities , net , were $ 4.2 million primarily due to litigation expense associated with a private shareholder lawsuit related to the 2006-2007 stock option investigation . in 2009 , we recorded reimbursements of $ 12.3 million from the insurance carriers and received $ 4.5 million from former executives as part of their settlement agreements with us in connection with the derivative and class action lawsuits in 2009. for the year ended december 31 , 2009 , recoveries of restatement and related legal activities , net , were $ 13.5 million due primarily to recognition of insurance settlements of $ 12.3 million from the insurance carriers and the receipt of $ 4.5 million from former executives as part of their settlement agreements with us in connection with the derivative and class action lawsuits . the $ 16.8 million was recorded as recoveries of restatement and related legal activities . until all the litigation and related issues are resolved , we anticipate that there could be additional amounts relating to these matters in the future . 39 gain from settlement : years ended december 31 , 2009 to 2010 2008 to 2009 2010 2009

for a multiple element arrangement , we are required to determine the fair value of the elements . we considered several factors in determining the accounting fair value of the elements of the settlement with samsung which included a third party valuation using an income approach , the black-scholes option pricing model and a residual approach ( collectively the fair value ) . the total gain from settlement is $ 133.0 million of which $ 126.8 million was recognized for the year ended december

liquidity our management continues to believe that total cash , cash equivalents and marketable securities will continue at adequate levels to finance our operations , projected capital expenditures and commitments for the next twelve months . cash needs for 2010 were funded primarily from operating activities due to the settlement with samsung as well as financing activities due to proceeds from issuance of common stock pursuant to the stock purchase agreement with samsung and from the issuance of common stock under our equity incentive plans . operating activities cash provided by operating activities of $ 235.2 million in the year ended december 31 , 2010 was primarily attributable to the signing of samsung and elpida . in total , samsung and elpida provided approximately $ 300.2 million of net operating cash flow after applicable foreign tax withholdings . additionally cash provided by operating activities included increases in accrued salaries due to the 2010 cip and bonus related to the samsung settlement which was offset by decreases in accrued litigation and accounts payable . cash used in operating activities of $ 40.6 million in the year ended december 31 , 2009 was primarily attributable to the net loss adjusted for certain non-cash items including stock-based compensation expense , non-cash interest expense , depreciation and amortization expense . changes in operating assets and liabilities which included decreases in accrued litigation expenses due to recognition of proceeds of $ 5.0 million from an insurance company related to the derivative and class action lawsuits offset by increases in accounts payable due to the timing of vendor payments .
