Introduction to the Patent System Quick history: see casebook Purpose of system: “to promote the progress of science and the useful arts” Importance of claims in understanding how patents work

Basic patent procedure File for patent in Patent and Trademark Office (PTO) Examiner assigned to application; 2-4 year process to obtain patent (on average) Final rejections can be appealed to administrative board in PTO

Court review of PTO Can appeal adverse ruling of PTO Board of Appeals to an appellate court Before 1982: Court of Customs and Patent Appeals (CCPA) 1982 and after: US Court of Appeals for the Federal Circuit (unified patent appeals court)

Who is Chakrabarty? Ananda Chakrabarty, PhD is a distinguished professor of microbiology and immunology at the University of Illinois College of Medicine. His most notable creation is a biology-based solution for cleaning up toxic spills using the generically engineered Pseudomonas (today classified as Burkholderia cepacia or B. cepacia).

Chakrabarty: Claims Process claims “Inoculum” including a carrier (combination claim) “the bacteria themselves”

Chakrabarty Claims: p A bacterium from the genus Pseudomonas containing therein at least two stable energy-generating plasmids, each of said plasmids providing a separate hydrocarbon degradative pathway.

Chakrabarty How many different types of claims?

Chakrabarty How many different types of claims? WHY?

Chakrabarty Process claims – never a problem –Why not? Process comprising steps of (1), (2), (3), where (2) involves living subject matter

Combination claims “An inoculum”... Also allowed Why?

SUBJECT MATTER § 101 Inventions Patentable 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.

Subject Matter: Overview § 101 Categories Process Machine Manufacture Composition of Matter Improvements

History of Section Act – “authored by Thomas Jefferson” -- ? Edward C. Walterscheid, The Use and Abuse of History: The Supreme Court’s Interpretation of Thomas Jefferson’s Influence on the Patent Law, 39 IDEA 195 (1999).

Section 101 Categories in Chakrabarty Manufacture Composition of Matter –“chemical union or mechanical mixture”

The now-famous punch-line Legislative history  statutory language, 1952 Act –“Anything under the sun that is made by [humans]”

Laws of nature Physical phenomena Abstract ideas What are the limits?

The Court’s examples of unpatentable things “a new mineral discovered in the earth, or a new plant found in the wild” Einstein’s “law” (E=mc 2 ) Newton’s law of gravitation

How is Chakrabarty’s oil- eating bacterium different? “His claim is not to a hitherto unknown natural phenomenon, but to a nonnaturally ocurring manufacture or composition of matter – a product of human ingenuity...”

Contrast (?) with Kalo Combining species into convenient plant-root inoculant How is this different from Chakrabarty’s invention?

What are the limits? “not nature’s handiwork, but his own” –How does this limit the scope of patent law? –Is it predictable? Too open-ended?

Counter-arguments Plant-specific Acts Congress should make IP policy, not the courts

What about plant-specific Acts? Implicit argument: –Expressio unius/exclusio alterius?

Somebody owns your genes. Through the U.S. patent system, corporations and universities have claimed property rights not just on the rice and corn at your dinner table but also on you. Moving beyond patenting and "owning" diseases like staph, tuberculosis, and SARS, one American corporation owns the genetic heritage of the entire population of Iceland. A university has property rights on all human clones-even though human cloning is still being debated in Congress. Another company claims to have invented "junk" DNA. Through its patents, it stakes a claim to the research on 95% of human DNA.

Though we are only at the earliest stage of the establishment of patent monopolies over genes, cell lines, and even organisms, the current struggle over access to AIDS drugs is a harbinger of problems ahead. AIDS drug costs are a clear example of the use of patent monopolies to drive up the price of therapy.

Jokichi Takamine

Jokichi Takamine was born on November 3, 1854 in Takaoka, Japan. He graduated from the college of science and engineering at the University of Tokyo in That year the Japanese government selected Takamine as one of 12 scholars to pursue graduate studies in Scotland at Glasgow University and at Anderson College. He returned to Japan in 1883 and joined the department of agriculture and commerce.

Takamine (cont’d) He worked for the department of agriculture and commerce as chief of the division of chemistry until At that time he formed his own company, the Tokyo Artificial Fertilizer Company, where he later isolated a starch-digesting enzyme, Takadiastase, from a fungus.

Takimine (cont’d) In 1894 Takamine moved permanently to United States, settling in New York City. He opened his own private laboratory but allowed Parke, Davis & Company to produce Takadiastase commercially. In 1901 he isolated and purified the hormone adrenalin in his laboratory, becoming the first person to accomplish this for a glandular hormone. --- Am Chem Soc’y, J. Chem Ed Online

Takamine: The Legend

Takamine’s patents ‘176 Product patent –Why was this valuable? –Why not a process patent (see Chakrabarty)

Takamine’s patents (cont’d) ‘177 Patent –“Salt” (acid) form of isolated hormone –Usually “salt” is applied to an ionic compound produced by reacting an acid with a base. –Why not at issue here? Claims were amended during prosecution. How could it have been valid? –Prior art

Judge Hand’s Decision

Hand’s decision “While it is of course possible logically to call this a purification of the principle, it became for every practical purpose a new thing commercially and therapeutically.”

Hand’s Pragmatism “Practical differences” Vs. “Scholastic distinctions”

Hand “But even if it were an extracted product without change, there is no rule that such products are not patentable...”
