While the US Congress continues debate on new patent reform legislation that would likely limit the amount that aggrieved parties could receive in infringement suits, the Supreme Court has agreed with a Justice Dept. request to hear a critical case. Its outcome, one way or the other, may not only impact technology patent law but also how manufacturers mix Intel and AMD parts, and also how - believe it or not - how digital music stores sell MP3 tracks.

The case was originally brought by LG Electronics, which manufactures a part for use in Intel-based communications equipment. LG holds a US patent on that part, which was expressly designed to be used with Intel chips; and Intel sells those chips under license from LG. One of Intel's customers is Quanta, a Taiwan-based computer manufacturer and the original defendant in this case. It assembles systems for Hewlett-Packard, among others.

Quanta wanted to be able to purchase parts from Intel, but use them in its own designs - which may involve parts from suppliers other than Intel. Under the terms of the original license, LG prohibits the use of the part for any other kind of design. When Quanta persisted, LG sought to charge Quanta royalties on its sale of computer equipment. When Quanta balked in 2000, LG filed suit.

In that original suit in district court, LG didn't claim that the Intel parts themselves violated its patents, but that the way Quanta chose to use those parts did, saying in its original suit, "the licensed Intel products meet many of the limitations of the patents and, when combined with other components in the accused devices, infringe five of its patents."

LG lost that suit, with the district court judge ruling that, while LG's license to Intel of its patent rights was legitimate, LG could not then exercise those rights "against those who legitimately purchase and use the Intel microprocessor and chipset." In other words, once that product ships, it's up to the customer to decide what to do with it, not the inventor.

The concept is called the first-sale doctrine, and it's actually a guiding principle of American intellectual property law. In essence, its purpose is to protect the rights of the customer who purchases licensed technology.

But although it's a doctrine, it's not really a law per se. That's why on appeal by LG, the district court ruling in favor of Quanta was partly overturned. Specifically, the part that matters concerns patent "exhaustion" - whether LG's rights stop at the shipping dock after Quanta resells it equipment to HP. The district court ruled that patent rights are "exhausted" after that first sale, in this case from Intel to Quanta.

But the appeals court ruled that LG's license of its IP to Intel was with the full knowledge that Intel would be reselling LG's technology to other parties, rather than manufacturing computers for itself. After all, Intel doesn't put its own brand on computers (not in the US, at least), so what would the value of a patent license to Intel actually be if it didn't extend all the way to the system builder? Since LG and Intel agreed upon that value, and that agreement is not in dispute, the appeals court ruled that government shouldn't try to decide what that agreement is for or how far it extends.

As the appeals court put it, "It is more reasonable to infer that the parties [Intel and LG] negotiated a price that reflects only the value of the 'use' rights conferred by the patentee." In other words, the price reflected how Quanta and other Intel customers might use LG's technology, not how Intel would use it.

Last month, Solicitor General Paul Clement petitioned the Supreme Court to hear Quanta's appeal of the overturned ruling, arguing very strongly on Quanta's behalf. "The patent law grants to the patent holder the 'right to exclude others from making, using, offering for sale, or selling the invention,"' Clement wrote, citing US Code. "This Court repeatedly has made clear that the exclusive rights to use or to sell are exhausted, as to a given article embodying the invention, upon the first valid sale of the article in commerce, whether by the patentee itself or by an authorized licensee... Thus, under this Court's cases, a patentee who sells a machine embodying the invention (either directly or through an authorized licensee) cannot bring a patent infringement suit against the purchasers for using the machine for its only reasonable use or for reselling the machine to others."

Clement went on to suggest that how resale customers should be excluded from using patented technology should be a matter determined by individual contracts between the parties, but not reliant upon US patent law. He then warned the high court that lower court rulings such as the overturning on appeal in LG's favor directly contradicted Supreme Court precedent.

So this dispute affects the rights of companies that assemble others' parts to design machines as they will, without finding themselves owing royalties to someone they've never done business with. It also affects the rights of inventors to sell to other companies, perhaps in other countries, with safeguards that their work will always be used as they originally intended. But whose rights come first? It is a huge question without any easy answers.

The link to music

At the beginning of this piece, I mentioned the outcome may also affect how MP3 tracks are sold by music stores. Although MP3 has little or nothing to do with the specifics of this case, its outcome will either affirm or deny the first-sale doctrine, which has everything to do with digital music sales.

See, some online music stores can be considered resellers just like Quanta. When they purchase tracks from music publishers, it contains licensed technology. Without the first-sale doctrine in place, if those stores then resell those tracks in a way the licensee didn't intend - for instance, changing the encoding or altering the DRM - the end customer could conceivably be held liable for how they use or listen to that music. In a very-worst-case scenario, they could owe royalties.

As a Duke University Law School brief argues, the first-use doctrine perhaps should not apply to "digital phonorecords," as the law calls them, because in order for an online music store or other service to present its customer with a phonorecord, duplication of the file must exist along the way, perhaps several times if you count copying to RAM and then copying to disk.

Each of those copies is protected under US copyright law, and constitutes a transfer of some kind - it's that fact which substantiates recent high court rulings against P2P distributors such as Grokster. Current prohibitions against unlicensed redistribution of digital music rely on the legal definitions of those transfers.

Since there are multiple transfers, Duke University argues, the first-use doctrine cannot apply.

But if the Supreme Court makes a broad ruling in favor of the first-use doctrine, as the Solicitor General suggests, music resellers as big as iTunes could conceivably affirm their rights - in court if necessary - to package music they've purchased however they wish, with or without DRM. That would change the whole meaning of digital rights management, perhaps threatening the very foundation on which the industry is based: resale of its technology for future use by others. This will be a huge case to watch.
