1. A method of optimizing therapeutic efficacy for treatment of an immune-mediated gastrointestinal disorder, comprising:
(a) administering a drug providing 6-thioguanine to a subject having said immune-mediated gastrointestinal disorder; and
(b) determining the level of 6-thioguanine in said subject having said immune-mediated gastrointestinal disorder,
wherein the level of 6-thioguanine less than about 230 pmol per 8x108 red blood cells indicates a need to increase the amount of said drug subsequently administered to said subject and
wherein the level of 6-thioguanine greater than about 400 pmol per 8x108 red blood cells indicates a need to decrease the amount of said drug subsequently administered to said subject.
The CAFC imports limitations into the claims to make their determination that it is statutory.
I could make a very solid argument this doesn't pass 101. First off, the "transformation" argument CAFC makes (which is: eating something inherently causes some type of transformation of the body), makes the transformation test absolutely useless because everything under the sun is now a transformation. Me thinking about something abstract just transformed neurons in my brain, 101 eligible!
The big elephant in the room regarding 101, and I believe I've said this before, is that you have two sets that claims can be in. Set1: claims that should be patent eligible under 101; and Set2: claims that should not be patent ineligible under 101. Every couple years the courts create some "test" that defines the boundaries of the Set3: set of patent eligible claims, which also defines Set4: set of patent ineligible claims. And the test(s), which define the Set3 and Set4, allegedly creates Set3 and Set4 so that they are identical (or near as can be) to sets Set1 and Set2, respectively. But every couple years a court realizes the deficiencies of a prior "test" by recognizing something in Set3 or Set4 that should or should not be in Set1 or Set2, respectively. And so they change or create tests all willynilly.
Well I can create tests too. For me, one thing I like to think about, especially when analyzing a method claim, is "Can a human being, by themselves, perform this method?"
Now, I don't have any idea what 6-thioguanine is, I'm not a chemical guy. But a couple things I notice about this claim that are red flags:
1) It makes no difference whether the subject has or doesn't have a particular disorder because the subject will either have or not have the disorder.
2) The wherein clauses at the end aren't positive steps to the method, and the numbers listed (pmol per blood cell) aren't a necessary accuracy amount for anything within the claim. That is, no measurement with a particular accuracy is occurring, these numbers just... exist... and "indicate" something.
3) The "determining" step doesn't require a machine as the CAFC alleges because there is no recitation as to what degree or accuracy or relativity the level is being determined.
4) The words "administrating" and "drug" may import particular definitions depending on the art and specification. I'm going to give them a fairly broad interpretation (I'm not one skilled in the art).
Now let's assume that 6-thioguanine is naturally occurring and that the phrase "administering a drug" could be a step based on a naturally occurring substance, maybe a person eating a plant or... sunlight hitting a person. So yes, let's assume 6-thioguanine is something that can be administered via sunlight. So step 1, we've got a person standing in the sunlight.
Then we've got a determining step that determines a level of that 6-thioguanine. No regard to accuracy or anything. So I get some sunlight which I know has 6-thioguanine, and now I determine I have more 6-thioguanine than I previously did 2 seconds ago, so I just determined the level of my 6-thioguanine relative to my prior level of 6-thioguanine. Specifically, I determined the current level is "more than" the last level. So step 2, we've got a person thinking about how much substance they have.
Now the wherein clauses, they've got some particular accuracy, but aren't positive step recitations, they're just knowledge that exists in the claim. So let's assume I'm the person and I just happen to know and keep in my brain that information. I know that my 6-thioguanine level (if I could measure it with awesome accuracy) should be more than 230 pmol per 8x108 and less than 400 pmol per 8x108 red blood cells.
So I just described to you a person, that stands in the sunlight (or eats some plant), that knows that the sunlight (or plant) contains 6-thioguanine and so they determine their level increases. And the person is also smart and knows their 6-thioguanine level (if they could measure it) should be more than 230 pmol per 8x108 and less than 400 pmol per 8x108 red blood cells.
Is that 101 eligible?
