AMENDMENT TO PATENT LICENSE AGREEMENT

EXHIBIT 10

AMENDMENT TO PATENT LICENSE AGREEMENT

THIS AMENDMENT TO PATENT LICENSE AGREEMENT (“Amendment”) is entered into effective as of November 13, 2002 (the “Effective Date”), by and between InterTrust Technologies Corporation, a Delaware corporation (“InterTrust”), and Sony Corporation, a Japanese corporation (each a “Party” and collectively, the “Parties”).

BACKGROUND

The Parties have previously entered into a PATENT LICENSE AGREEMENT effective as of May 20, 2002 (“Agreement”).

By this Amendment, the Parties desire to expand the rights granted to Sony by the Agreement, in particular for InterTrust to grant to Sony a royalty free, fully paid-up, nonexclusive license in all fields under the Licensed Patents for Sony products and services in accordance with the terms of this Amendment.

In light of Sony’s world-wide preeminence and potential to be a market-maker for the relevant technology, which will be of value to InterTrust in future licensing, InterTrust is willing to grant and grants this paid-up license at a discounted amount.

AMENDMENT

1. Definitions. Unless expressly defined herein, all capitalized terms used in this Amendment shall have the meanings defined in the Agreement. Should there be an inconsistency between this Amendment and the Agreement, the definitions set-forth in this Amendment shall prevail.

(a) “Licensed Products And Services” means (i) any and all processes, activities, software, programs, machines, articles of manufacture, compositions of matter and any other products or services marketed under Sony Trademarks, (ii) any finished self-contained consumer electronic hardware appliance (such as TVs, set-top boxes, and portable CD players) that are made by Sony and distributed to a third party for distribution by such third party under such third party’s trademark, provided that such devices are substantially the same as an equivalent appliance distributed by Sony under a Sony Trademark (such as a finished DRM-enabled portable disc player made by Sony and distributed to Sharp Corporation for sale by Sharp under a Sharp brand with only changes in outside appearance and branding, provided that Sony also distributes a substantially similar disc player under a Sony Trademark); and (iii) Licensed Products And Services also includes (and not by way of limitation), Sony Products, Sony Trust Services, Sony DRM Commercial Services, Sony Third-Party DRM Commercial Services and Sony Customer DRM Commercial Services.

(b) “Licensed Patents” means all valid, enforceable and unexpired patents and patent applications throughout the world under which patents or applications therefor InterTrust at any time owns, or possesses the right to grant the licenses to Sony within the scope granted herein subject to the following. With respect to any patents owned by any third party (that were not previously owned by InterTrust) for which InterTrust has a license and the right to sublicense subject to the payment of a fee or royalty to such third party, Licensed Patents will include such third party patents provided that Sony agrees to pay such license fees or royalties, and abide by relevant terms, as required to obtain such rights, after InterTrust has provided notice to Sony of such option. For licenses entered into by InterTrust after the execution of this Amendment where the patents licensed to InterTrust relate to the same general subject matter as any of the Licensed Patents, InterTrust will use commercially reasonable efforts to obtain sublicensing rights for Sony from such third party patent licensors; provided that Sony agrees to pay such license fees or royalties, and abide by relevant terms, as required to obtain such sublicense, after InterTrust has provided notice to Sony of such option. Sony acknowledges and agrees that there will be no liability in the event that InterTrust is unsuccessful after using such commercially reasonable efforts to obtain sublicensing rights for Sony. The term Licensed Patent shall also include any continuations, continuations-in-part, divisionals, reexaminations or reissues of any of the aforesaid patents or patent applications. Exhibit A sets forth a list of InterTrust existing published patent applications and issued patents, and upon Sony’s written request from time to time InterTrust will provide an updated list to Sony.

2. Patent License and Release

(a) Subject to the terms and conditions of this Amendment and of the Agreement pursuant to Section 4 below, InterTrust hereby grants to Sony a royalty free, paid-up, nonexclusive, nontransferable, and worldwide license under the Licensed Patents, in all fields, to make, have made, use, sell, offer for sale, lease, import, transfer, operate, distribute, otherwise dispose of and otherwise provide or have provided any and all Licensed Products And Services.

(b) Past Acts. InterTrust hereby releases Sony from any and all claims of infringement of any Licensed Patents with respect to any Licensed Products And Services, in any field, made, used, sold, offered for sale, leased, imported or otherwise transferred before the Effective Date of this Amendment to the extent licensed. InterTrust further releases Sony’s customers, distributors and end-users in connection with Licensed Products And Services provided by Sony prior to the Effective Date of this Amendment.

(c) Anti-circumvention. Each Party agrees that Sony is not licensed to distribute a product or technology component that: (i) is made available to third parties through any community source program or similar public domain initiatives; or (ii) can provide DRM functionality to a plurality of third-party applications running in an operating system environment, provided that the restriction set forth in this paragraph (ii) shall not apply to the Consumer Media Field. For avoidance of doubt, a Sony-branded turnkey dedicated

medical system that supports multiple networked medical devices with DRM functionality is not covered by the restriction set forth in Section 2(c)(ii).

3. License Fee and Payment Terms: Sony shall pay to InterTrust a non-refundable payment of six million U.S. dollars (US$6,000,000.00) within thirty (30) days of execution of this Amendment.

4. Survival of Agreement Terms: Other than as may be modified herein, all terms of the Agreement and any rights granted therein shall survive this Amendment, except for the following terms of the Agreement that shall be deemed void: Sections 2(b), 2(d), 2(e), 2(f), 3(b), 3(c), 3(d), 3(e), 3(f), 3(i), and 3(m). Except as set forth in Section 5, in the event of any inconsistencies between the terms of this Amendment and the Agreement, the terms of this Amendment shall prevail.

5. InterTrust Termination Election. Nine (9) months following the Effective Date, and for six (6) months thereafter (hereinafter the “Termination Period”), and provided that InterTrust, or any successor, assign, direct or indirect parent or subsidiary, or any of their respective affiliates (defined as either: (i) any entity that acquires twenty percent or more of the outstanding equity of InterTrust from a transaction entered into by InterTrust with the approval of the InterTrust board of directors; or (ii) one or more entities working in cooperation through a joint venture, contractual or otherwise collectively acquires more than fifty percent of the outstanding equity of InterTrust), is not: (a) marketing commercial products or services other than DRM reference designs or technology; or (b) licensing patents other than DRM patents, InterTrust may elect to terminate this Amendment by providing Sony with written notice thereof and paying to Sony a payment of six million U.S. dollars (US$6,000,000.00). Upon termination of this Amendment, the licenses hereunder terminate and any rights surrendered by Sony hereunder including those provided in Section 2(b) of the Agreement shall be immediately and automatically restored, with no further action or notice of the Parties or any other party being required, as of the date of such termination, and the Agreement shall continue in accordance with its terms as it existed prior to the Amendment; except that the products set forth solely in Section 1(a)(ii) of this Amendment shall be included in Sony Products under the Agreement and thereby licensed in accordance with the terms of Section 2(a) of the Agreement. For the avoidance of doubt, it is acknowledged that, as of the Effective Date, InterTrust is not marketing commercial products and services other than DRM reference designs and technology, and that InterTrust’s patent portfolio (including patent applications) are DRM patents.

6. Additional Rights to Memory Stick in the Event of No Termination. If at the end of the Termination Period InterTrust has (i) the right to terminate pursuant to Section 5 of this Amendment, but (ii) has not exercised such right, then Section 2(b) of the Agreement shall be immediately and automatically restored, with no further action or notice of the Parties or any other party being required, and the rights granted therein to Memory Stick and Memory Stick Capable Products shall be amended to include, but not be limited to, the Consumer Media Field.
