Quanta Computer V. LG Electronics: Reviving exhaustion, applying it to method patents

Monday, August 30th, 2010

Background LG Electronics (LGE) owns the rights to several patents on computer technology, which describe a computer operation or a method, not actual product. LGE licensed the patents to Intel Corporation a license agreement that authorizes Intel to manufacture and sell microprocessors and chipsets that use and incorporate the LGE patents. LGE and Intel had a separate agreement (“Agreement”) that required Intel to provide its customers in writing that the license does not extend to a product made by combining an Intel product with non-Intel product. The Framework Agreement provides that violation thereof does not affect the integrity and the terms of the license agreement. Quanta purchased microprocessors and chipsets from Intel, then builds computers using Intel parts in combination with non-Intel parts, but without changing the Intel parts. LGE sued Quanta, asserting that combination has infringed LGE’s patents. Quanta argued that LGE’s patents were exhausted when Intel sold Quanta parties that embodied LGE’s patents and thus LGE has no rights. The district court initially granted summary judgments in favor of Quanta, but on reconsideration, denied the summary trial on the grounds that the doctrine of exhaustion does not apply to method patents. The Federal Circuit held that patent exhaustion does not apply to method patents and, alternatively, found that LGE did not license Intel to sell Intel products to Quanta to combine with non- Intel. The U.S. Supreme Court heard the case Jan. 16, 2008 and issued its opinion, reversing the Federal Circuit, and find in favor of Quanta, June 9, 2008. The doctrine of exhaustion of patent and its history pre-Quanta The basic concept of exhaustion of patent law means that the first authorized sale of a patented item terminates all patent rights to that item. Quanta, 128 S. Ct at 2115. The doctrine is based on the notion that a patent is entitled to a single charge – allowing the first sale, the patentee has probably negotiated and obtained the value of patent rights. The Supreme Court has explained that the touchstone of the doctrine of exhaustion of patent is “whether or not there has been such a provision of the article, it can rightly say that the holder received reward for the use of the article. ” United States v. Masonite Corp., 316 U.S. 265, 278 (1942). In the early 1900s, some courts have allowed patentees to post-sale restrictions on their patents that have allowed them to control (and receive additional fees) in the channel downstream, long after the sale initial authorized. Quanta, 128 S. Ct at 2115-2116. But in 1917, the Supreme Court has clearly indicated that these restrictions after-sales would not be tolerated. In Motion Picture Patents Co. v. Universal Film Mfg. Co., 243 U.S. 502, 516 (1917), the Court held that “the right to sell is exhausted by a single, unconditional sale, the item being sold and is performed outside of the monopoly law patent and rendered free of any restriction which the vendor may attempt to set it. “ Before Quanta, preceding the most recent and important Supreme Court on the exhaustion doctrine, including its application components and method patents, has been United States v. Univis Lens Co., 316 U.S. 241 (1942). In Univis, the patentee (Univis Corp.) held a patent claim on a spectacle lens and contact lens manufacturing process by producing grinding and polishing lens blanks. Univis Corp. licensed its related company, Univis Lens, manufacture lens blanks. Univis Lens sold the license blanks to wholesalers and retailers who would finish grinding and polishing of blanks by the practice of the patented method Univis. Licenses for wholesalers and retailers contained strict limitations after purchase to which the lens blanks may be sold and at what price. The court found that when selling licensed Univis “of the lens blanks, which had no use except to practice realistic Univis patents, patent rights lens on the lens blanks and finished products were exhausted. “[T] he authorized sale of an item that is able to use that in practice the patent is an abandonment of patent monopoly with respect to the item being sold.” Univis, 316 U.S. at 249. The Court stated: ”Retailers of all first article manufactured under a patent puts the article beyond the scope of the monopoly conferred by patent. If the licensee sells the patented article in its full form or sells it before the end in order to enable the buyer to finish and sell it, he also departed from the article, and made the vehicle for the transfer to the buyer the ownership of an invention in respect of this article. To that extent, he has abandoned his patent monopoly in either case and has received the purchase price of all the advantages of this monopoly that the patent law provides him. S it was possible to control the price at which it could be sold by others, it would extend its monopoly in one case as much as in the other, and it would extend beyond the fair meaning of laws Patent and construction, which has hitherto been given. “316 U.S. at 252. Despite holding Univis, however, the Federal Circuit again allowed the erosion of the exhaustion doctrine by allowing patent holders to impose restrictions after-sales service and the limits of their patents. The seminal (and often criticized) to power in Mallinckrodt, Inc. v. Medipart, Inc., 976 F. 2d 700 (Fed. Cir. 1992), helped limit patentees to their customers significantly in the repair, renovation, recycling and modifying equipment post-sales – a violation of the restriction was an infringement of patent unless the restriction violated another law such as antitrust laws. The justification for detention, a patent holder to the merchant and receives royalties based on a planned and their use, if the buyer makes use of other auxiliaries and the patent, the patentee must be able to claim additional charges for non-negotiated employment. The decision of Mallinckrodt and its progeny have limited the right of the exhaustion of patents in various ways – a controversial result. Patent owners have relied on these cases by drafting license agreements that the Federal Circuit has interpreted as the preservation of their rights to file a complaint of infringement against downstream users who purchase and use the licensed product. Indeed, the Federal Circuit has applied this same line of thought when it upheld the District Court against Quanta. (1) In addition, from Mallinckrodt, also in apparent contradiction with the holding Univis, the Federal Circuit held that method claims are not subject to the exhaustion of patents. (2) The Federal Circuit has seriously weakened the doctrine of exhaustion by limiting only to claims of devices. Quanta Univis reaffirms and renews the doctrine of exhaustion In its decision in Quanta, the Supreme Court relied heavily on the precedent of Univis and definitively held that the exhaustion doctrine applies to method claims and apparatus claims. The Court said: “It is true that a patented method may not be sold in the same way as an article or device, but methods nonetheless may be” embodied “in a product, the sale of rights patent exhaustion. ” 128 S. Ct at 2117. The Court warned that any other result “would seriously undermine the exhaustion doctrine. Patented seeking to avoid patent exhaustion could simply draft their patent claims to describe a method rather than an appliance.” 128 S. Ct 2117. This technique is exhausted avoidance, if it were effective, would wreak havoc on downstream buyers, who may be suddenly responsible for patent infringement, unaware that a method incorporated in the product they have has purchased a patent inexhaustible. After verifying that exhaustion applies to method claims, the Court explained that “the extent to which a product must have a patent in order to trigger exhaustion.” Id at 2118. Again, the Court examined Univis guidance, concluding that when the licensed product that contains the patented method is really able to be used when we practice the patented method, exhaustion applies: ”As the lens blanks Univis, Intel products are an important part of the patented invention and all but completely practice the [LGE patent]. Here, as in Univis, the incomplete article substantially embodies the patent because the only necessary to practice the patent is the application of common processes or the addition of standard parts. Any inventive each patent is embodied in the Intel products. “128 S. Ct at 2120. LGE argued that exhaustion does not apply because the sale of Intel to Quanta was not “authorized” first sale. LGE argued that the contractual restriction after purchase it imposes on its patents – that LGE did not license Intel to sell Intel products to Quanta to combine with non-Intel – have prevented the application doctrine. 128 S. Ct at 2121. The Federal Circuit had agreed with this argument, following the precedent it had established for itself (which the parties can contract around the exhaustion) during the last 15 years. But the Supreme Court disagreed. LGE had two separate agreements with Intel a license agreement that granted Intel the right to manufacture and sell patents LGE, and a separate Master Agreement, which contained the restriction after purchase. But the specific framework agreement stated that its breach did not affect the validity of the license agreement. Consequently, the licensing agreement Intel has the authority to sell its products containing the patent LGE, and the first authorized sale exhausts LGE patents, regardless of the other agreement. Id at 2121-2122. Quanta leaves one question answered imperfectly There may be a question remains about the exhaustion when the component that embodies the patent has other uses non-infringement. For example, if the Intel products were thousands of non-infringing uses outside the LGE patented process, but someone has used the Intel patent practice LGE, an argument could be that exhaustion does s’ LGE should not apply and have the right to sue and infringement action against this user. It certainly was not the case in Quanta, the Intel chips really have no use, even while embodying the LGE patents until they are put into a computer and practical use of the patent . But what if the chips have been many other uses, only one has been the practice of patent LGE? Could exhaustion still apply? The foregoing indicates that the overwhelming exhaustion does not apply in such circumstances. But the opinion Quanta includes this curious comment: ”While each Intel microprocessor and chipset practices thousands of individual patents, including some LGE patents not at issue in this case, the analysis of exhaustion is not affected by the fact that more than one patent is practiced by the same product. The relevant consideration is whether the Intel Products that partially practice a patent – for example, embodying its essential features – exhaust that patent. “128 S. Ct. 2121. Insofar as this passage might suggest that a patented process can be exhausted, even if it is contained in a product with many legitimate uses, we believe it is simply incorrect wording by the court. Future cases may clarify the issue, more precisely, but the precedent should be lit obstacle to the application of exhaustion in this circumstance. (1) LG Electronics, Inc. v.

Glossary of Marine Electronics

Autopilots The first self-steering ratio has been set up in 1920 to control model yachts but it was not until 1948 that the principle has been applied to large scale yachts. Standing at the bar for long periods, monitoring instruments and keeping a good look, can be very tiring. An autopilot relieves the helmsman to steer the correct course leaving him free to maintain a proper lookout. The autopilot can be set to either steer a compass course or a course by the wind. A fluxgate compass or electronic vane feeds information to a microprocessor which then makes the necessary rudder movements to return the vessel to its required courses. The mechanical power is applied to the rudder by either electric linear activators, hydraulic pumps or rotary discs. GPS / card readers can be used to input navigation instructions to the autopilot. Battery Chargers will keep batteries fully charged thereby extending their working life. Chart Plotters Typically, a card reader comprises an antenna, mounted high on the boat, to track GPS signals and a display unit located either at the navigation station or the helm of ship. The boat position is sent from the antenna to the display unit, which in turn, shows graphically on the map. The table itself looks like its paper equivalent and show depth, land mass, navigational aids such as buoys and hazards in the form of wrecks and obstructions. The user can add waypoints to the map and zoom in and out of the screen. Card readers can be connected to drive an autopilot and / or send data to a GPS fish finder or radar. They can also interface with a laptop enabling complex passage planning to be away from the boat, then walked into the card reader after his arrival at the boat. Transmission Magnetic Compass work like traditional compasses using magnets to determine the direction of the magnetic field of ships land which they then send the boats to the electronic display. They are steering easier than conventional compasses because they display more stable position and do not suffer from “lag” that occurs during a turn. They can interface with card readers, autopilots and radar. Fluxgate compass composed of two pieces of magnetic material easily saturated with coils wound round them in opposite directions. The alternating current is passed through the coils and the material is saturated in one direction and then another. The Earth’s magnetic field affects slightly when the saturation occurs earlier in a coil, then the other. The difference is then calculated by taking an output proportional to the magnetic field of the earth. They are accurate to 0. 1 degree. Their output can be displayed digitally to the helmsman or they can interface with autopilots and radar card readers. Sounders work on the same principle as sonar. A transducer emits a narrow beam of high frequency sound. This is reflected by solid objects and the delay between transmission and reception of the echo is measured. The speed of sound in water is known and if the range or distance from the bottom of the sea can be calculated. Which is then displayed in meters. Forward Looking Sonar (FLS) enables you to see the underwater dangers before you actually above them. A typical range of FLS is 150 meters. An Emergency Position Indicating Radio Beacon (EPIRB) is a piece of equipment designed to float free of a ship in distress. It then sends a radio signal that can be detected by the search and rescue satellite Computer Aided Tracking (SARSAT) satellites. They send a message to a ground station which in turn may initiate a search operation and rescue. Fish finders use the same technology as sonar. A narrow beam of high frequency sound is transmitted by a sensor, which is reflected by solid objects such as the seabed. By developing this technology displays provide pollsters show where fish are and they can not differentiate between baitfish and larger speciesGlobal Positioning System (GPS Receivers) – This system was originally designed for military use and is owned and operated by the U.S. Department of Defense. 24 satellites are arranged in a bird cage “around the world, they are positioned so that anywhere on the surface of the earth line of sight can be set at a minimum of 4 satellites. A patch is obtained by accurately measuring the distance between a satellite and GPS receiver at a particular time. Because the exact position of the satellite is known, these distances provide position lines which are converted by a microprocessor in the GPS receiver to read outs of latitude and longitude. The log is used to measure the speed of boats in the water. A paddle wheel or impeller, mounted below the waterline is turned by water flow, which generates electrical impulses that are transmitted to a microprocessor that displays speed and distance traveled. Inverters – On most boats today you will find domestic equipment of one kind or another. For entertainment there are televisions on board and stereos. With the popularity of card readers is the PC or laptop. Maintenance often requires the use of power tools. Cruise could have a washing machine, dishwasher or microwave. May take 12V 24V or 48V supply and convert it into a stable 110 V or 220 V AC. Navtex can perhaps best be described as a telex service provides continually updated navigation and weather information within specified areas. A board on the receiver, tuned to 518kHz, frequency Navtex worldwide, if left turned on will either print or display the latest massages sent from a local station. The service is available up to 400 miles offshore . Radar lets you see what otherwise would be invisible. They offer more advantages in the night and in fog or rain and are of particular value when close to the coast or sea routes. They are made of an antenna and a screen. The antenna sends a stream of RF energy which is reflected by hard objects. When this energy is returned, it is converted into a signal that appears to the user. The antenna rotates every few seconds, the display continuously calculates the direction of the antenna and so a precise impact of the target is calculated. The time is measured by the energy to be taken into account and if the distance of the target is also displayed . Satellite phones consisting of an antenna, a modem and a regular phone. They are powered by a battery of iridium. Their range is anywhere covered by the Inmarsat Mini-M satellite. Voice, fax, email and data can be transmitted. satellite TV requires an antenna and of course television. The reception is available in a “fingerprint” that is based on EIRP (equivalent isotropic radiated power) of a satellite transmission. EUTELSAT satellites with ASTRA two cover Europe. Nilesat and Arabsat cover both Africa and the Middle East. Good coverage is also available in North America, Central and South America. SSB Radio has a range of several thousand miles. You need an FFC license, or equivalent in any country you plan to run it. Energy consumption is a consideration. Up to 100 Watts may be necessary for transmission. SSB radio requires several pieces of equipment. A transceiver capable of operating SSB, an antenna, it must be 8 meters long and in practice most boats use a backstay or shroud for the purpose of equipping the necessary insulation. A antenna tuner, the model transceiver. If you want to send an email, and you will also have a radio modem and computer. VHF power needed to transmit is minimal, every game has the possibility of transmission each 1 Watt or 25 Watts and less energy should be used whenever possible. Unlike phones that can both speak and listen at the same time most VHF sets require you to press a button issue before speaking. This is called simplex. Duplex sets are available but are much more expensive. VHF radio waves travel in straight lines, so the antenna must be mounted as high as possible, preferably masthead.

Wednesday, August 11th, 2010

AP November 18, Chi Mei Hon Hai to TaiwanÉlectroniqueChong Group announced its merger, the new CMO is expected to become Korea SudSamsung, LGComposer with a panel of three main mondial.Samsung 8. 7 billion U.S. warning Chi Mei Mo “proud” to CMO “strong words” Samsung panel to consolidate the leading position in the global market, the external confirmed yesterday that he would spend 10 billion won ( about 8. 7 billion U.S. dollars) has continued to expand its production capacity of the previous panel. According to the survey company believes that Samsung in the next 3-4 years should continue to maintain the leading position of the production capacity of panels. It is understood that Samsung plans to invest in 2011-2015 above principal place of concentration soup Park in Taiwan. However, equipment manufacturers, according to the statement of the panel, Samsung 7. 5-Generation plant in Suzhou, China plans talks recently with the equipment manufacturers are also very hot, it is expected to more than 90,000 monthly production capacity meant that the continent will also be three weeks followed a layout. industry estimates, 87 million of investment, nearly nine 3 8. 5 Capacity plant, apparently Samsung’s investment plan for follow-up mercilessly. Layout, particularly in mainland China. Insiders pointed out that we all know that the Government may establish panels of full opening of the next generation, the future may be that the house will be 4-5 to approve the establishment, which led to the recent Mainland Chinese manufacturers continue to announce their position on the map on the phenomenon 8. 5 plant. But in reality, the future of these claims a number of plans to build a factory, how few can really achieve the government and financial resources? Probably not yet finalized. Terry Gou said the solar industry 8:00 A question of fact, and even China’s economy mondialeHome AppliancesLes companies have launched the 8th generation, 8. 5 on behalf of the onlineThe gateway, screen LCDl’argument of excess capacity has been one after another. November 18 China has invited the Ministry of Industry panel to guard against excess capacity. Now, Samsung shouted 8700000000 worth of investment projects. Terry Gou said the panel industry is at 8 am the sun just rose, “at an early stage, huge development potential. He believes the industry can do a lot of money that money makes little first and second and third time at the loss of profits, and the rest of the big pay a small profit. Must be the top three. According to DisplaySearch statistics, in terms of size of the glass substrate to determine how market rate of capacity this year, Samsung’s market share of about 24%, primarily in world. Even in 2013, Samsung is market share with 22% of the market dominate the overall picture. The Chi Mei has announced the merger news, current capacity of approximately 17% of estimated market over the next 4 years also maintain the same level. How this return not to participate in the merger of AU Optronics, approximately 16% market share this year, but the future, it will gradually fall to 14%. Research firm iSuppli market also noted that Samsung Q3 this year to find the United States from competitors, VizioTV LCDMarché to win the title mainly due to Samsung LCD basLEDTV offer. Third quarter of this year, shipments of Samsung LCD TVs in the United States has reached 1. 3 million units, eating about 17% of the market, shipments of Vizio T3 approximately 120 million units, the market share of approximately 16%.

LPC2368 microprocessor and the first physical layer chip DP83848C briefly presented, then given based on LPC2368 for the design of equipment Ethernet interface, the document describes the process of implementing software. 1 Introduction With the rapid development of Internet technology, sharing information on demand is also rising. Currently, embedded systems have penetrated every corner of our lives is the perfect combination with the network of information sharing that we offer a great convenience. Philips is a good company LPC2368 microprocessors, embedded systems based on its Ethernet interface, otherwise the application will also greatly reduced. Thus, the entire system, the Ethernet interface circuit must be indispensable, but it is also relatively complex. Ethernet interface circuit mainly from the MAC controller and interface physical layer (PhysicalLayer, PHY), two major parts. LPC2368 integrated Ethernet controller, support for the rationalization of the interface (the Independent Media Independent Interface ReducedMedia, RMII) and the DMA buffer interface (Buffered DMAInterface BDI), half-duplex and full duplex mode, providing 10M/100Mbps of Ethernet access. Therefore, LPC2368 internal fact already includes Ethernet MAC control, but did not provide a physical layer interface, therefore, necessary to add an Ethernet physical layer chip to provide the access channel.
