On the day I visited the Supreme Court, it heard two cases each for an hour: Tapia v. United States concerning sentencing for rehabilitative purposes, and Microsoft v. i4i Limited Partnership concerning the standard of proof in evaluating patents for invalidity.

Tapia v. United States

Background

Alejandra Tapia and a friend were passing through customs while driving from Mexico to the United States. An immigration official noticed they were acting nervously and took a closer look at their car, discovering two illegal immigrants that Tapia was attempting to smuggle into the United States. She was arrested for this but was soon released, subject to court restrictions, while proceedings continued. When she failed to appear in court for a hearing, a warrant was issued for her arrest. After later apprehension Tapia was convicted on counts related to her smuggling of illegal immigrants and for jumping bail.

The judge responsible for sentencing her thought she would benefit from a particular drug treatment program, offered only in certain prisons. In order to get her into that program, he recommended Tapia be sent to a particular prison, and he increased the length of her sentence explicitly to give her the opportunity to take part in that program. In doing so he potentially fell afoul of this statutory language:

The court, in determining whether to impose a term of imprisonment, and, if a term of imprisonment is to be imposed, in determining the length of the term, shall consider the factors set forth in section 3553(a) to the extent that they are applicable, recognizing that imprisonment is not an appropriate means of promoting correction and rehabilitation.

The issue

Before enactment of the law adding this language, the “rehabilitative ideal” as implemented by U.S. law held that isolation from society and prison routine would rehabilitate criminals. Parole boards determined when prisoners were ultimately released based on subjective assessments of the progress of inmates. The Sentencing Reform Act changed the system to be more objective, while still attempting to leave judges discretion to determine individualized sentences.

The sticky wicket is in the phrase, “recognizing that imprisonment is not an appropriate means of promoting correction and rehabilitation”. Does “recognizing” this mean that when a district court sets a length and term of imprisonment, he can’t consider rehabilitation programs in determining the sentence length? If he can’t consider them, then perhaps Tapia’s sentence was wrongly lengthened. On the other hand, section 3553(a) explicitly says, “The court…shall consider…the need for the sentence imposed…to provide the defendant with needed educational or vocational training, medical care, or other correctional treatment in the most effective manner”, which arguably includes drug treatment programs like the one recommended for Tapia here. How should the “recognizing” clause be understood?

Further wrinkles in this particular instance include that Tapia wasn’t sent to the recommended prison (because doing so would place her in too close proximity to another inmate deemed likely to be a bad influence) and that she wasn’t entered into the recommended drug treatment program (as I understand it, because she refused to be enrolled). So the judge in question (more generally, any judge, as I understand it) couldn’t actually have required her to enroll in a treatment program as part of her sentence.

Laws and decisions to consider

This is mostly a case of statutory interpretation of existing laws, so there’s not much in the way of prior Supreme Court decisions to consider. It mostly comes down to how you read the text of the relevant statutes. One statute beyond those above that I find particularly interesting is 28 U.S.C. § 994(k), which states:

The Commission shall insure that the guidelines reflect the inappropriateness of imposing a sentence to a term of imprisonment for the purpose of rehabilitating the defendant or providing the defendant with needed educational or vocational training, medical care, or other correctional treatment.

The guidelines in question specify sentencing ranges from which judges generally can’t depart. Interestingly, this section seems pretty clear that sentencing to a term of imprisonment for the purpose of providing the defendant with access to “correctional treatment” (like a drug treatment program) is not acceptable. If §3582’s text is ambiguous, perhaps this text might clarify it.

Microsoft v. i4i Limited Partnership

Background

In the 1990s i4i received a patent on a method of storing a document whose contents are structured, say, by formatting, nesting, and so on. Broadly speaking, the patent proposes storing document contents separate from document structure to facilitate easier manipulation. (The exact trick is pretty much this: store all the textual contents of the document somewhere, then store a list of pointers into that text with associated semantic meanings, like begin-element or end-element, separately.) The idea apparently works well when used in editors, and Microsoft once (no more, due to this litigation) used it in the custom XML editor built into Word. i4i sued them for doing so, and while Microsoft claimed the patent was invalid, the jury didn’t buy it. Microsoft was required to pay i4i $200 million for infringing their patent, then $40 million for doing so willfully. (Apparently Word developers had seen a presentation from i4i about software practicing the patent, asked questions about how it worked, received marketing material from i4i that mentioned the patent by number, and discussed i4i’s marketing material in email.) With interest the total’s now around $300 million.

The issue

Microsoft pled their case up through the courts, losing at each level. Finally they appealed to the Supreme Court — but because Microsoft’s particular travails aren’t necessarily interesting to the Supreme Court as it can only selectively right wrongs (it reviews around 1% of ten thousand or so appeals every year), Microsoft tried an interesting tack: they challenged the standard of proof required to demonstrate invalidity of the patent. This got the Supreme Court to bite and hear their appeal.

The district court told the jury that Microsoft had to prove invalidity by clear and convincing evidence, a phrase not found in statutory text but rather inferred from 35 U.S.C. § 282. Microsoft argues that when the standard of proof is unspecified, the default (with rare exceptions not relevant here) is a preponderance of the evidence. Clear and convincing evidence basically means the claim is “highly probable”; a preponderance of the evidence basically means the claim is “more likely than not”, or “50% plus one”. It could be much easier for Microsoft to prove invalidity if they only had to get a jury to say that the patent in question was more likely than not (by even the smallest fraction) to be invalid.

(What was Microsoft’s evidence of invalidity, you ask? Here it turns into a mess. i4i sold software called S4 over a year before applying for the patent, and S4 might have implemented the patent in question. If S4 implemented the patent, then an on-sale bar in 35 U.S.C. § 102(b) would invalidate the patent. Microsoft and i4i disagreed about whether S4 practiced the patent. [S4’s source code, and presumably S4 itself, was no longer available to be inspected, as S4 had been obsolete before litigation commenced.] Microsoft said S4 implemented the patent, citing the software’s manual, testimony from a former i4i employee, and a letter i4i’s founder wrote to investors indicating that S4 implemented the idea he later patented. i4i’s founders said it didn’t, and one stated in court that the musings in the letter to investors were “an exaggeration, and as I said, it could be said to be a lie” and that the idea was conceived after S4 went on sale. Without S4’s source code Microsoft couldn’t prove invalidity by “clear and convincing evidence”. But it’s quite possible Microsoft could prove it was “more likely than not” that the on-sale bar applied, and that the patent was invalid.

Microsoft also attempted to claim invalidity of the patent by dint of its being obvious through combination of a couple other patents, one of which the examiner who granted i4i’s patent hadn’t seen. Should a patent be “presumed valid” in the language of the statute, and in the lower court’s understanding thus requiring clear and convincing evidence to prove invalid, if the evidence for invalidity wasn’t considered when the patent was granted? Here too could be another avenue of attack under a favorable ruling.)

Laws and decisions to consider

This case, as like Tapia, is mostly a matter of statutory interpretation. But beyond the clauses of patent law at issue there are also a few Supreme Court decisions of relevance.

First, in 1934 in RCA v. Radio Engineering Laboratories, Inc. Justice Cardozo variously described the burden to overcome a patent’s presumption of validity as “clear and cogent evidence”, that the challenger “bears a heavy burden of persuasion, and fails unless his evidence has more than a dubious preponderance”, and that “the countervailing evidence is clear and satisfactory”. (Microsoft distinguishes this language as referring to particulars of that case, specifically that the evidence being tried there had been tried once by one party and found wanting, then in that case was being tried again by an entirely separate party — so “clear and convincing” makes sense only in that rare situation.) Justice Cardozo’s opinion, and its language, precede the statutory text used to justify the clear-and-convincing standard: does the text merely codify that precedent? (Of course, Microsoft and i4i furiously disagree about what the precedent says, and about how courts interpreted that standard.) This case cuts for i4i.

Second we have Grogan v. Garner and Herman & MacLean v. Huddleston. In Grogan the former Justice Stevens, analyzing a case where the statutory text was silent about the standard of proof, determined the standard to be a preponderance of the evidence. In Justice Stevens’s words, “This silence is inconsistent with the view that Congress intended to require a special, heightened standard of proof.” In Huddleston Justice Marshall determined the standard of proof in a similar situation to be a preponderance of the evidence. These cases cut for Microsoft.

Third we have KSR v. Teleflex, a 2007 Supreme Court patent case. In passing in that case, Justice Kennedy wrote in dicta for a unanimous Court that “the rationale underlying the presumption—that the PTO, in its expertise, has approved the claim—seems much diminished” in a case where the PTO hadn’t considered evidence being used to challenge a patent. So perhaps the presumption of validity that Microsoft was challenging shouldn’t apply (or should apply with lesser force) because the PTO didn’t know about the software Microsoft claims implemented the patent. This would cut for Microsoft.

Past this you have the usual arguments for and against patents: Microsoft saying that granting patents too easily is dangerous (an interesting position for them, perhaps), and i4i saying that the patent system stimulates innovation and that invalidating patents hurts that. (Each side’s argument pretty much completely ignoring the patent system’s inherent balancing act between incenting progress and retarding it.) How much weight you want to give this depends to an extent on what sort of partisan you are.

Next time, to the arguments themselves.
