Novelty and Loss of Right; §102
- §102(a): prior art must be by another; default date of current invention (DOI) is the effective f/d; may be overcome by Rule 1.131 or Rule 1.132 declaration depending on the situation.
- General elements: conception, reduction to practice(RTP), reasonable due diligence
- Actual RTP: testing is not required
- Constructive RTP: filing patent application; DOI = f/d
- Reasonable due diligence: until RTP, before prior art date
- Four §102(a) prior art events that anticipate a claim before the date of invention (not f/d)
- Public knowledge inside US: known to others
- Not deliberately concealed
- Classified material’s public knowledge date = printing date (but not yet made public!)
- Used by others inside US
- Not deliberately concealed
- Patented anywhere in the world: patent date = patent publication date
- Both claims and specification in earlier patent are prior art.
- In US: patent date = patent publication date = patent enforcement date
- In a jurisdiction where patent right is attached before patent is published: patent date = patent publication date
- In a jurisdiction where patent right is attached after patent is published: patent date = patent publication date
- Printed publication anywhere in the world: key is public open-access and dissemination
- Printed prior art must enable
- Library housed publication: must be catalogued/indexed by subject, or otherwise sufficiently accessible to the public.
- Magazine or journal disseminated by mail: received by at least one member of the public
- Internet posting: considered printed publication
- Classified material’s printed publication date = release date (made public, later than its public knowledge date)
- Oral presentation: considered printed if written copies distributed without restriction to an open audience
- Earlier publication when applicant is one of multiple authors: is prior art
- Public knowledge inside US: known to others
- Overcoming §102(a) rejection
- Submit Rule 1.131 declaration antedating applicant’s invention
- Submit Rule 1.132 declaration showing that the prior art of another actually describes the current applicant’s invention.
- General elements: conception, reduction to practice(RTP), reasonable due diligence
- §102(e): secret prior art; may be either a published application (§102(e)(1)) or a US patent (§102(e)(2)); prior art must be by another (= prior inventive entity not completely identical to current entity); prior art date is a US date (not foreign priority date); prior art patent must be enabling; may be overcome by a Rule 1.131 or Rule 1.132 declaration.
- Published domestic application §102(e)(1)
- Prior art date is the earliest US f/d (provisional f/d, nonprovisional f/d, or domestic priority date) of an earlier US application.
- Foreign priority date is not a prior art date: Hilmer doctrine
- An applicant’s foreign priority date may be used as a “shield” to protect his own patent application.
- A reference inventor’s foreign priority date may not be used as a “sword” to defeat another inventor’s patent application.
- PCT application published by WIPO in English §102(e)(1)
- Prior art date is the PCT f/d if the PCT application also:
- Was filed on or after 2000-11-29 (AIPA)
- Designated the US
- Was published by WIPO in English (after PCT f/d)
- If the PCT application does not satisfy the above 3 conditions, then its prior art date is only its publication date, thus only serving as §102(a) and/or §102(b) prior art.
- This prior art date may be pushed even further if this PCT application
- Claims priority to an even earlier US application (provisional or nonprovisional), but not foreign application!
- Still satisfies the above 3 conditions
- This reference published PCT application does not need to enter US national stage.
- Prior art date is the PCT f/d if the PCT application also:
- PCT application following US national stage entry, published by PTO in English §102(e)(1)
- Prior art date is the PCT f/d if the PCT application also:
- Was filed on or after 2000-11-29 (AIPA)
- Designated the US
- Was published by WIPO in English (after PCT f/d)
- If the PCT application does not satisfy the above 3 conditions, then its prior art date is only its publication date, thus only serving as §102(a) and/or §102(b) prior art.
- Prior art date is the PCT f/d if the PCT application also:
- US patent issuing from a domestic application §102(e)(2)
- Prior art date is the earliest US f/d (but not foreign priority date) of an earlier US patent.
- US patent issuing from a PCT application following national stage entry §102(e)(2)
- PCT application filed on or after 2000-11-29 (post-AIPA)
- Prior art date is either the PCT f/d or an earlier effective US f/d, if the PCT application:
- Was filed on or after 2000-11-29 (AIPA)
- Designated the US
- Was published by WIPO in English (after PCT f/d)
- If the PCT application does not satisfy the above 3 conditions, then its prior art date is only its issue/publication date, thus only serving as §102(a) and/or §102(b) prior art.
- Prior art date is either the PCT f/d or an earlier effective US f/d, if the PCT application:
- PCT application filed before 2000-11-29 (pre-AIPA)
- Prior art date is the US national stage entry date, thus the applicant must have done the following:
- Paid the requisite national fee
- Filed a copy of the PCT application and English translation (if necessary)
- Filed the requisite oath or declaration
- Not necessary: WIPO published the PCT application in English (reason: such publication is a product of AIPA)
- Prior art date is the US national stage entry date, thus the applicant must have done the following:
- PCT application filed on or after 2000-11-29 (post-AIPA)
- Published domestic application §102(e)(1)
- §102(g)(2): comparing two DOIs by different inventors inside US
- Prior art must be by another
- Prior art date is before the current applicant’s DOI
- Another’s invention was not abandoned, suppressed or concealed: even without public access
- Prior art must be inside US
- Prior art invention must have been reduced to practice, actually or constructively
- §102(b): statutory time bar; prior art date more than a year prior to current f/d
- General elements
- Compare prior art date with the critical date (one year before current US f/d)
- If one-year anniversary of prior art date falls on a weekend or federal holiday, then filing on the next PTO business day is timely.
- §102(b) time bar may be created by current applicant’s own prior art.
- Current invention claim must read on prior art (every element and limitation of current claim must be present in the prior art).
- Four prior art events that anticipate the critical date (one year before f/d) of current claim
- In public use inside US: even single, unobservable event qualifies
- Not intentionally concealed
- Public use in violation of confidentiality agreement is nonetheless public use.
- Experimental use in public (to demonstrate feasibility) is not public use.
- Public testing necessary
- Must be technical in nature
- Experiment kept confidential
- Profit only incidental to use
- Market testing is considered public use.
- On sale inside US: commercial sale or offer for sale; invention must be “ready for patenting” (= ARTP or enabling)
- Profit is irrelevant.
- Sale or offer for salt to or from US, even when the offer was rejected by or was not received by the offeree, even when the sale was never consummated.
- Assignment of patent rights is not an on sale event.
- Same as public use: experimental use is not on sale, but market testing is on sale.
- Published abstract that is non-enabling may establish on sale event.
- Patented anywhere in the world: same as §102(a)
- Printed publication anywhere in the world: same as §102(a)
- In public use inside US: even single, unobservable event qualifies
- A §102(b) statutory time bar cannot be overcome by any means.
- General elements
- §102(d): pertains to foreign prior art patent only; similar to §102(b) time bar; cannot be overcome by any means
- Foreign patent must be filed more than 12 months (6 months for designs) before the US f/d.
- Foreign patent must issue before the US f/d.
- Foreign must have been filed by the same inventor, his legal representative or assigns (such as company, employer, etc.)
- The same invention must be involved, but not necessarily claimed in the US application and foreign patent.
- §102(c): applicant has abandoned the invention; abandonment requires intent (expressed or implied) by the inventor
- Intent to abandon type one: unreasonably long delay in applying for US patent, coupled with other evidence of intent to abandon (such as being spurred on by another’s commercialization of the invention)
- Intent to abandon type two: obtaining a US patent disclosing but not claiming a distinct embodiment of the invention: presumed to dedicate to public; may be overcome by a later application within a year from publication or by recapture through broadening reissue within two years from issue.
- Mere abandonment of application is not abandonment of invention
- May revive application if unintentionally or unavoidably abandoned the application
- May reacquire application if expressly abandoned application, but loses original f/d
- §102(f): applicant derived the invention from another (did not conceive the invention)
- Geography is irrelevant to derivation
- Special forms of §102 prior art
- Abandoned applications: unpublished application; MPEP901.02, MPEP2127
- If an issued patent refers to an abandoned application, the contents of the abandoned application becomes §102(a), (b) prior art as of the patent’s issue date.
- If an issued patent incorporates by reference an abandoned application, the contents becomes prior art under §102(e)(2) prior art as of the patent’s filing date.
- Material cancelled from an application during prosecution: becomes §102(a), (b) prior art when the patent issues.
- Reason: prosecution history becomes public when the patent issues.
- Not §102(e)(2) prior art because it is not disclosed in the patent itself.
- Incipient §102(e) references: later filed application may be provisionally rejected over an earlier application under §102(e)
- If the two applications have a common inventor or assignee MPEP2136.01
- If different inventor or assignee, then PTO cannot break confidence and disclose.
- Statutory Invention Registration (SIR): treated as §102(e)(2) prior art as of f/d.
- Doctrine of forfeiture: from case law, similar to §102(b)
- Commercial, purposely hidden use of a process or machine more than a year before f/d, coupled with secret sale of offer to sale: precludes the applicant from obtaining patent.
- But the hidden use and sale does not preclude a later, third-party inventor from obtaining patent of the same invention.
- Abandoned applications: unpublished application; MPEP901.02, MPEP2127
- Noted points
- Anticipation, inherency, enablement
- Current invention claim must read on prior art: every element and limitation of current claim must be present, expressly or inherently (evidenced by a second reference), in the prior art.
- Anticipation requires enablement by PHOSITA, but such enablement may be evidenced by a second reference.
- The second reference only demonstrates, but does not supplement.
