Subject matter:
patent law protects inventions — not just knowledge. A trade secret claim can be defended against with reverse engineering, or independant creation (and defense of copyright) — these defenses are not valid with patents. Patent has set duration – 20 years from date of application – trade secret is good until not secret. Trade secret just exists — patent must be filed at PTO and in every other country — and patent must be issued. A trade secret must be secret, patents are published. Patent law promoted disclosure, trade secret does not. Copyright and Trademark law are agnostic.
Eligabiltiy for trade secret is broad – patent has the four requirements plus subject matter.
Patent is more difficult, but scope of rights is stronger. A patent prevents others from making, selling, using, constructing, assembling, or inducing.
infringement requirements: trade secret – must show wrongfully obtained and used. patent -validity of patent and infringement: accused product or device reads in the patent, either literally or in equivalence.
Trade secret is a state right, patent is a federal right – patent suits must be filed in proper venue. appealed in fed circuit court of appeals in DC – not in the circuit – to promote uniformity of law. trademark can be fed or state and appeal like normal cases.

How do you get a patent? Once you get it, you might not get to keep it — in court it can be challenged, seek to invalidate. Patent is a probalistic property right — noone know if it will stand legal defense. Patents are used to fluff up company value – many challenged patents – a high percentage – get overturned in court.
Constitution protects discoveries of inventors and writings of authors to give congress the power to write patent and copyright – not trade secret or trademark laws. Art I Sec 8.
Constituition promotes invention and discovery that promote useful arts (or tech development) — gives monopoly to patent recipient, justified by idea that reward of patent will appeal to man’s greed and spur inventiveness. Thought better than other justifications. Without patent it would be too easy for people to copy inventions for their profit — the problem of ‘public goods’ – so we give patent monopoly.
Patent has serveral parts – specification and claims – specifications describe invention, claims define scope of invention – what is excluded. Claims alone delimit right to exclude, only claims can be infringed. The disclosure is in public domain. It is said that claims must be read in light of specification especially if there is ambiguity. The patent code 112 sets 3 requirements for disclosure –
1. description – invention claimed must be invent described –
2. enablement – description must be in full and clear and concise terms description such that to allow one skilled in the arts to build
3. best mode – best embodiment known at time of application
Requirements for patentability
35 U.S.C.
SS 101 Utility – whoever invents or discovers a new or useful process, machine, manufacture, or composition of matter, or any new or useful improvement thereof may obtain a patent subject to other requirements.
Process art or method – includes new use of known process of — could be method for making someting or a process for using something, or a method for doing something. inventor may invent process or product or both at the same time. Process patent excludes others from making object at issue by same/similar process. Does not exclude making same product with different process.
Product patent broader. Machine, manufacture, or composition of matter- generally products,but some may fit in one or more categories
machine – it does something, every mechanical device, or mechanical power and device, to perform some function producting a certain result
manufacture-production of activces for use from or prepared, giving materials new properties. clothing, furniture, food all fit.
composition of matter all compositions of 2 or more substances and all composite whether chemical or mechanical mix or be gasses fluids powders or solids – human genes,
Excluded subject matter – laws of nature, certain physical phenomena (naturally occurring) or abstract ideas
SS 102 Novelty
SS 103 non-obviousness
SS 112 Enablement
Rights Conferred by a Patent
Diamond v. Chakrabarty, 447 U.S. 303 (1980)
A live, human-made micro-organism is patentable subject matter under [Title 35 U.S.C.] 101. Respondent’s micro-organism constitutes a “manufacture” or “composition of matter” within that statute. patentable becasue it is new – unique, isolated, not repeated by nature, and cannot be reproduced by nature
Dissent: Court should not extend patent protection beyond congress – they could have done so if they wanted to.
Chakra made process to create bacteria that can eat oil. arguement that it was a product of nature was rejected. board held that living things were not patentable — supreme court rejected – alive or dead is not the question. manmade is the question. What makes a living thing human made?
Parke-Davis &Co. v. H. K. Mulford Co. – NY Southern District Court 1911
- Purified preparation of Natural products can be patented as a product (not just a process) in some cases, if they are a new thing commercially and improved therapeutically.
- Natural products are not patentable, man made manipulations are
Brenner v Manson – US Supreme – 1966
Utility – manson wanted to patent chemical compound that had no know use – board said utility was not demonstrated. court of custom and patnet appeals sait utility need not be shown as long as it is not against public welfare – supreme said this is not sufficient – process must produce product that is useful. product must have utility, otherwise process that is new and novel cannot be patented.
In re Fisher – Fed Circuit – 2005
fisher patented ESTs – marker genes are intemediaries not end products, used in experimentation, not a “final product”. Only useful as a research tool mostly. No indication that it will lead to a product.
Patent: The written description requirement. One of several disclosure requirements in patent law.
Spec describes invention, claims set forth bounderies of what is excluded by patent.
Sec 112 simplified:
1. spec shall contain written description of invention
2. enablement
3. best mode
Section 112 reads:
The specification shall contain a written description of the invention, and of the manner andprocess of making andusing it, in such full, clear, concise and exact terms as to enable any person skilled in the art to which it pertains . . . to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Possession Test: The “possession” test therefore means, in effect, that if you are going to focus on a feature or aspect of the disclosed technology in the claims, you need to indicate that in the specification itself.
Enablement Test:
The Gentry Gallery, Inc. v. The Berkline Corp.
Gentry issued patent for sectional sofa that had recliners facing the same direction and controls for both in a console between the reclining chairs. Berkline made sofas with two recliners with the controls under the cushion. Patent focused on the console. Berkline made recliners without a console, so patent was not viiolated.
Written description in spec only mentions controls on a fixed console.
Written Description Biotech notes: For a time courts requires specific gene sequences – a patent for mouse inselin contained sequenced, but cliamed to cover human insulin. This was rejected because genes should have been disclosed (Lilly). Another case upheld patent of broad class of cells that produced a novel protein
Holding: Ammended claims cannot exceed the original specification
Pioneers: Generally it is the policy to allow pioneers broad protection for inventions, said to promote progress in the useful arts.
“Best Mode Requirement”
a statutory bargained-for-exchange by which a patentee obtains the right to exclude others from practicing the claimed invention for a certain time period, and the public received knowledge of the preferred embodiments for practicing the claimed invention
Best Mode Test:
1) the factfinder must determine whether, at the time the patent application was filed, the inventor had a best mode of practicing the claimed invention
2) Once it is established that the inventor actually contemplated a best mode, a court will inquire whether the disclosure in the patent spec is adequate to enable one of ordinary skill in the art to practice the best mode of the invention
Novelty and statutory bars
Novelty means “new compared to the prior art” — an invention has to be new to get a patent.
Statutory Bar – ” a bar to patentability based on too long a delay in seeking patent protection” — wait too long on publishing, disclosing, or making and no patent for you.35 U.S.C. 102
Conditions for patentability; novelty and loss of right to patent.
A person shall be entitled to a patent unless –
(a) the invention was known or used by others in this country, or patented or described in a printed publication in this or a foreign country, before the invention thereof by the applicant for patent, or
(b) the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country, more than one year prior to the date of the application for patent in the United States, or
(c) he has abandoned the invention, or
(d) the invention was first patented or caused to be patented, or was the subject of an inventor’s certificate, by the applicant or his legal representatives or assigns in a foreign country prior to the date of the application for patent in this country on an application for patent or inventor’s certificate filed more than twelve months before the filing of the application in the United States, or
(e) the invention was described in – (1) an application for patent, published under section 122(b), by another filed in the United States before the invention by the applicant for patent or (2) a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent, except that an international application filed under the treaty defined in section 351(a) shall have the effects for the purposes of this subsection of an application filed in the United States only if the international application designated the United States and was published under Article 21(2) of such treaty in the English language; or
(f) he did not himself invent the subject matter sought to be patented, or
(g)(1) during the course of an interference conducted under section 135 or section 291, another inventor involved therein establishes, to the extent permitted in section 104, that before such person’s invention thereof the invention was made by such other inventor and not abandoned, suppressed, or concealed, or (2) before such person’s invention thereof, the invention was made in this country by another inventor who had not abandoned, suppressed, or concealed it. In determining priority of invention under this subsection, there shall be considered not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, from a time prior to conception by the other.
Sec 102:
Novelty and Loss of Right
We have a first to invent system (opposed to first to file system)
102a Novelty – “anticipation” – a bar to the validity of a patnet that exists when the disclosure of a single piece of prior art reveals everty element of a claimed invantion. If there is anticipation then there is not novelty.
102b “critical date” – One year prior to applicant’s filing date – key to loss of right
Rosaire v National Lead Co. – 5th Circuit Appeals – 1955
2 guys developed tech to discover petroleum by searching for traces of hydrocarbons in areas. Gulf Oil said that they had already developed the process and used a bit years earlier, never publicized, but not ‘hidden’. patent not granted.
NOTES: “The nonsecret use of a claimed process in the usual course of producing articles for commercial purposes is a public use.”
To anticipate prior knowledge or use in this country it must be accessible by the public. vs It need not be published, just must not be affirmatively hidden.
To show prior use, there is a a stringent requirement — getting your relatives and having a bad inconcluseive picture just won’t cut it.
Novelty under 102a vsnonobvious under 103: 102a single piece of prior art reveals every element, 103 combined prior art references can defeat non-obviousness
Inherency Doctrine
Accidental anticipation of an invention does not bar patenting.
In Re Hall -Fed Cir 1986
Applied for patent, rejected on statutory bar for publication. Held that disertation, with only one copy in a university library in Gernmany is published enough to start one year clock for staturtory bar.
For determining 102b a single copy accessible to members of the public interested in finding the information is a publication.
Cronyn – invented chem compunduseful to treat cancer, rejected as anticipated in student thesis prior to critical date. Court found they were not printed because they were not accessile (in re hall indexed, cataloged, and shelved)
cannot get patent if wait more that one year after invention was put on sale or in public use or described in publication.
Invention given or sold without limitation or restriction or promise of secrecy or confidentiality,
then control has been relinquished.
Egbert v Lippman – US Supreme 1881
Man improved steel bars inside corset, shares with girlfriend and then years later applies for patent, denied because sharing with friends constitutes puiblic use (say because there was no confidentiality agreement.).
City of Elizabeth v Pavement Company:
invented processs for building wooden road. he put 75 in place for 6 years on toll road given patent because he monitered for wear and tear every day and the road was under his control. court said that road can only be tested over a long period of time for wear and tear in public
If sale is primarity for experimental purposes then htat use does not trigger public use bars. a secret commercial use may be fatatl — an experimental use in public may not trigger bar. length of testiing, no of tests, records kept of test, and results and feedback. Were those who performed test obligated tosecrecy, testing must berelated to claimed featureadn not some other part. a market test to see iff consumerswill buy is not anexperimental use — it is a commercial test.
Offer to sell does not trigger “on sale” bar if item offered for sale was not available — only if the invention meets: ready for patentating – reduced too practivce by buiolding a model or inventor has sufficient drawings or descriptions that one skilled in art could build model.
