Opinion

ORDER GRANTING DEFENDANTS’ MOTION FOR PARTIAL SUMMARY JUDGMENT

CLAUDIA WILKEN, District Judge.

Defendants Hitachi, Ltd., Hitachi America, Ltd., Hitachi Data Systems Corp. and Hitachi Computer Products (America), Inc. (collectively, Hitachi), move for partial summary judgment on Plaintiff LG Electronics, Inc.’s (LGE) infringement claims with respect to a subset of the accused products. LGE opposes the motion. The matter was heard on February 26, 2009. Having considered oral argument and all of the papers submitted by the parties, the Court grants Hitachi’s motion.

BACKGROUND

LGE charges Hitachi with infringing four of its patents: U.S. Patent Nos. 4,939,641, 5,379,379, 5,077,733 and 4,918,-645. The same patents were the subject of litigation in this Court between LGE and a number of computer manufacturers. That litigation was eventually appealed to the United States Supreme Court. The Supreme Court described the technology embodied in the first three of the patents as follows:

The data processed by the computer are stored principally in random access memory, also called main memory. Frequently accessed data are generally stored in cache memory, which permits faster access than main memory and is often located on the microprocessor itself. When copies of data are stored in both the cache and main memory, problems may arise when one copy is changed but the other still contains the original “stale” version of the data. The '641 patent addresses this problem. It discloses a system for ensuring that the most current data are retrieved from main memory by monitoring data requests and updating main memory from the cache when stale data are requested. The '379 patent relates to the coordination of requests to read from, and write to, main memory. Processing these requests in chronological order can slow down a system because read requests are faster to execute than write requests. Processing all read requests first ensures speedy access, but may result in the retrieval of outdated data if a read request for a certain piece of data is processed before an outstanding write request for the same data. The '379 patent discloses an efficient method of organizing read and write requests while maintaining accuracy by allowing the computer to execute only read requests until it needs data for which there is an outstanding write request. Upon receiving such a read request, the computer executes pending write requests first and only then returns to the read requests so that the most up-to-date data are retrieved.
The '733 patent addresses the problem of managing the data traffic on a bus connecting two computer components, so that no one device monopolizes the bus. It allows multiple devices to share the bus, giving heavy users greater access. *1039 This patent describes methods that establish a rotating priority system under which each device alternately has priority access to the bus for a preset number of cycles and heavier users can maintain priority for more cycles without “hogging” the device indefinitely.

Quanta Computer, Inc. v. LG Elecs., Inc., — U.S. -, 128 S.Ct. 2109, 2113-14, 170 L.Ed.2d 996 (2008) (citations omitted).

Although the '645 patent was the subject of proceedings in this Court and in the Federal Circuit on appeal, LGE did not pursue its infringement contentions with respect to the '645 patent in the Supreme Court. In its decision, the Federal Circuit described the technology embodied in that patent as follows:

The '645 patent discloses a digital computer system that has devices called agents that are interconnected by a system bus. The claimed system and corresponding method require one agent, the requesting agent, to request access to a memory stored on another agent, called the replying agent. The requested data is organized as a matrix of memory cells, having column and row coordinates. The “memory controller” of the replying agent processes the request from the requesting agent by asserting a plurality of memory address control signals, including at least one row address strobe (“RAS”) signal and one column address strobe (“CAS”) signal. This “page mode memory access” operates by the assertion of an entire row of data followed by the assertion and deassertion of multiple column addresses. By the RAS signal accessing an entire row followed by the assertion and deassertion of particular column addresses, this page mode memory access differs from the conventional memory access, which separately accessed each memory cell by asserting its individual row address and column address. In the claimed invention, after the data is accessed, it is then transferred to the requesting agent over the system bus.

LG Elecs., Inc. v. Bizcom Elecs., Inc. (Bizcom), 453 F.3d 1364, 1373 (Fed.Cir.2006).

On September 7, 2000, LGE entered into a license agreement with Intel Corporation. Pursuant to this agreement, Intel paid to LGE a certain sum of money and agreed to provide an additional amount in discounts on future purchases. It also gave LGE a license to its own patents. In exchange, Intel received a “fully paid-up, worldwide license” to the technology in LGE’s patents, including the four patents at issue here. The same license agreement was involved in the Quanta litigation. The Supreme Court described the relevant provisions of the agreement as follows:

The License Agreement authorizes Intel to “make, use, sell (directly or indirectly), offer to sell, import or otherwise dispose of’ its own products practicing the LGE Patents. Notwithstanding this broad language, the License Agreement contains some limitations. Relevant here, it stipulates that no license “is granted by either party hereto ... to any third party for the combination by a third party of Licensed Products of either party with items, components, or the like acquired ... from sources other than a party hereto, or for the use, import, offer for sale or sale of such combination.” The License Agreement purports not to alter the usual rules of patent exhaustion, however, providing that, “[njotwithstanding anything to the contrary contained in this Agreement, the parties agree that nothing herein shall in any way limit or alter the effect of patent exhaustion that would otherwise apply when a party hereto sells any of its Licensed Products.”
In a separate agreement (Master Agreement), Intel agreed to give written notice to its own customers informing them *1040 that, while it had obtained a broad license “ensuring] that any Intel product that you purchase is licensed by LGE and thus does not infringe any patent held by LGE,” the license “does not extend, expressly or by implication, to any product that you make by combining an Intel product with any non-Intel product.” The Master Agreement also provides that “a breach of this Agreement shall have no effect on and shall not be grounds for termination of the Patent License.”

Quanta, 128 S.Ct. at 2114.

The defendant computer manufacturers in Quanta had purchased microprocessors and chipsets from Intel and received the notice required by the Master Agreement.
