Historical Overview of Patent Law
United States
Article I, Section 8 authorizes Congress “to promote the progress of science and useful arts, by securing for limited times to authors and inventors the exclusive right to their respective writings and discoveries”
35 USC 261: Patents have “the attributes of personal property” but are not property themselves
Patent Claim Drafting Exercises
Transition
‘Open’ Claims:“Comprising elements A,B,C” = claim covers any embodiment of the invention having the elements A,B,C and any additional elements
“Closed” Claims: “Consisting of elements A,B,C” means that a variant that includes A,B,C & D doesn’t infringe
In-between format: “Consisting Essentially Of”
Could cover a variant on the elements only if the added element did NOT make the variant essentially different from the claimed invention (so those with insignificant additions are in the scope, those with significant modifications are not)
The Body
Three Formal Requirements for Claim Drafting
Entire claim must be stated in the form of a single sentence
Claim must set forth how each element interacts with at least one other element
Any internal references must be clear
Independent and Dependent Claims
Means-Plus-Function Claims: “Means for doing X” - covers the corresponding structure, material, or acts described in the specification and equivalents (it covers many but not all means)
Can only be used in combo with at least one other element
Overview of Patent Rights and Patent Process
Patent Process
Apply
PTO examiner negotiates with you
Afterwards, you can seek a reissue (if you think claims were too narrow) or anyone can seek a reexamination
3 AIA proceedings that allow patent challenges to challenge validity: Inter Partes Review, Post-Grant Review, Covered Business-Method
No presumption of validity here
All decisions made during examination are subject to review by PTAB (and then by Fed Cir or commencing a civil action in DC against director of PTO)
Judicial Actions: Infringement and Declaratory Judgment Suits
Once patent has been issued, lawsuits can arise in two ways
Patentee brings infringement action against accused infringer
Potential infringer files a declaratory judgment action against patentees (to challenge validity of patent rather than waiting to be sued by patentee)
Can file this when there is a “reasonable apprehension of a lawsuit”
Patents enjoy presumption of validity here
General
Section 101: "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title."
Patentability issues treated as threshold issues to be decided by PTO and courts early in their processes
Diamond v. Chakrabarty (1980)
Issue: whether a live, human-made microorganism is patentable subject matter under 101
Patentee could claim the bacteria because the distinction is not between living and nonliving but is between products of nature vs. man-made (bacteria was man-made)
Court holds that 101 uses broad terms, and thus Congress contemplated the laws would have broad scope. But there are limits:
The three judicially created limits
Laws of nature
Physical phenomena
Abstract ideas
Something doesn’t necessarily need to be explicitly declared patentable by Congress to be patentable
Whether a subject matter is patentable cannot depend on whether it would be good policy or not
Dissent
Bilski v. Kappos (2010)
Method for hedging risks put into math formula
REJECTS Machine or transformation test: which says that an invention is only a process if (1) it is tied to a particular machine or apparatus or (2) it transforms a particular article into a different state or thing
DENIED: Court can’t read into patent laws limitations (must read ordinary meaning), and adopting the MOT test violates that (because there’s no ordinary meaning of process that requires MoT).
MoT can be a TOOL but is not sole test
REJECTS Categorical exclusion of business methods patents
DENIED: Method is within the definition of “process”
Plurality: There needs to be a high bar set for business methods (they raise special problems of vagueness and suspect validity)
NOT patentable because it is an attempt to patent abstract ideas (and its application to different markets)
Diehr- while an abstract idea, law of nature, or mathematical formula can’t be patented, an application of a law of nature, or mathematical formula to a known structure or process may well be deserving of patent protection (need to consider the invention as a whole)
Flook- can’t circumvent an unpatentable thing by just limiting it to a particular environment (basically just providing the formula bc everything else was known)
Notes
Per se categorical rules rejected for open-ended standards
Within 3 excluded categories- courts freely cite cases from one exclusion while talking about the others
Mayo Collab. Services v. Prometheus Labs, Inc.
Claim: give drug, measure metabolites, use that to determine if high/low and adjust. Process wasn’t patentable (because steps added were conventional & it was just a common-sense application of the law of nature)
Though things that contain laws of nature/natural phenomena/abstract ideas might be okay, because all patents at some level rest on these, to transform an unpatentable law of nature into a patent-eligible application, you need to do more than just “apply it” or add conventional steps. Process must contain some inventive concept sufficient to ensure that it is more than just a law of nature
More than just adding in an “administering” step
When all elements are added together, there must be more than just the law of nature + already known things
Diehr: used a known math equation to determine when to open molding press (patent eligible because the steps themselves integrated into the process were not conventional or in use)
Neilson- application of natural laws (patented a furnace that was designed to take advantage of a newly discovered natural principle; wasn’t patenting the principle itself)
Notes
Mayo applies for the scope of all three exclusions
Policy for exclusions: no inventive part, monopolizing tools and inhibiting further discovery by typing up laws of nature etc.
Mayo Framework:
Step one: Determine whether the claims at issue are directed to one of the patent-ineligible concepts (the three exceptions)
Step two: examine the elements of the claim to...
