Nonobviousness; §103
Nonobviousness; §103
- Most common §103 rejection: §103(a)
- Prior art under §103
- All §102 events MPEP2141.01
- Admissions made by the applicant MPEP2129
- Labeling drawing as prior art even though the subject is not prior art
- Written admission during prosecution even when later recanted
- Jepson-type claim’s preamble: implied prior art, but may be overcome
- Factual inquiries to determine the obviousness of the subject matter as a whole. The four Graham factors are: MPEP2141
- Determine the scope and content of the prior art
- Ascertain the differences between the prior art and the current claim
- Resolve the level of PHOSITA in the pertinent art
- Evaluate secondary considerations – objective indicia of unobviousness
- Commercial success
- Long felt but unresolved needs
- Recognition of problem solved
- Failure of others to solve the problem
- Competitor’s prompt copying
- Licensing of patent to industry
- Teaching away from prior art
- Unexpected results
- Disbelief and incredulity of others
- Typical §103 rejections
- Combining references: claim is rejected under §103 over Reference A in view of Reference B
- Modifying a reference: claim is rejected under §103 over Reference A because it is well known in the art and therefore obvious to make the modification recited in the claim.
- Examiner asserts “well known” or “common knowledge” in the art: applicant may challenge and examiner must respond with reference for support
- Examiner asserts personal knowledge: applicant may challenge and examiner must respond with affidavit for support
- Prima facie obviousness; MPEP2142
- Purpose for establishing prima facie upon §103 rejection: to protect against using hindsight when the applicant discloses his invention; only facts from prior art may be used (no hindsight).
- Prima facie obviousness is established when: PHOSITA combine or modify prior art teachings to produce current invention, with 3 criteria listed in the following MPEP2143
- First, there must be suggestion or motivation in the prior art itself or in PHOSITA’s knowledge to modify or combine MPEP2142.01
- Mere “can be modified or combined” won’t do; must have motivation
- Combination or modification cannot destroy the intended function, or change the operation principle of the prior art
- Combination or modification cannot teach away from prior art
- Applicant’s discovery of the problem or the source of the problem may defeat prima facie obviousness.
- Second, there must be reasonable expectation of success MPEP2143.02
- There must be reasonable, not absolute degree of predictability.
- Predictability is evaluated at the time the invention was made (no hindsight).
- Finally, all claim limitations must be taught or suggested by the prior art in order to establish prima facie obviousness (basic idea: current claim reads on prior art). MPEP2143.03
- Important: it is not necessary that the prior art suggest the same advantage or result accomplished by the invention (i.e., prior art may have a different motivation)! Motivation in the prior art to combine and modify may be implicit!
- Modified or combined prior art must be analogous to the current invention: same field as current invention, or pertinent to the current problem addressed
- Circumstances supporting an obviousness rejection MPEP2144.04
- Changing size, shape, or sequence of adding ingredients
- Reversing, duplicating, or rearranging parts
- Making portable, integral, separable, adjustable or continuous
- Omitting an element and its function
- To rely on equivalence as a rationale to support a §103 obviousness rejection, the equivalents must be recognized in the prior art, and cannot be based on applicant’s disclosure or the mere fact that the components at issue are equivalents.
- First, there must be suggestion or motivation in the prior art itself or in PHOSITA’s knowledge to modify or combine MPEP2142.01
- Procedure of PTO prima facie obviousness rejection:
- Examiner bears the initial burden to factually support the prima facie obviousness rejection.
- If the examiner fails to produce a prima facie case, applicant may ignore.
- If the examiner succeeds in producing a prima facie case, then the burden shifts to the applicant.
- Applicant may counter the prima facie obviousness rejection by submitting additional evidence, such as commercial success, unexpected result, etc. (see Graham factors: objective indicia)
- Rebutting a prima facie obviousness rejection: uses secondary, objective indicia; must be based on facts; argument alone will not suffice
- Commercial success MPEP716.03: must be due to relevant advantages of the invention and not because of promotion or advertising
- Increase market share : strong evidence
- Increased sales due to relevant advantages of the invention: increased sales alone is insufficient.
- Mere conclusory statements or naked opinions are insufficient.
- Evidence of unexpected results as compared with prior art
- Commercial success MPEP716.03: must be due to relevant advantages of the invention and not because of promotion or advertising
- Prior art under §103
- §103(b) rejection: biotechnology process
- Never relied on in practice because Federal Circuit overruled it.
- A known process that makes novel product(s): the process is patentable under §103(b) but was overruled in court.
- A known process that uses novel material(s): the process is patentable under §103(b) but was overruled in court.
- §103(c) rejection: to foster team/joint invention
- For applications filed on or after 1999-11-29 (post-AIPA)
- Reference subject matter developed by another, that qualifies as prior art only under §102(e),(f),(g) [secret prior art, interference, derivation] shall not preclude patentability under obviousness rejection if at the time of the invention:
- The invention was owned by or assigned to the same entity
- Inventors were under joint research agreement and were disclosed as such
- Noted points
- Claim interpretation (for §102 and §103 rejections)
- During examination, claims are given their broadest reasonable interpretation in light of the specification, so that they may read on by prior art. MPEP2111
- Reading a claim in light of the specification is not the same as reading the limitations of the specification into the claim.
- Claim terminology is interpreted by PHOSITA, unless otherwise defined in specification. MPEP2111.01
- Limitations not recited in a claim must not be imported into a claim, unless in a mean-plus-function claim.
- Preamble is generally not limiting, unless
- In a Jepson-type claim
- Essential to understanding the claim
- Argued during prosecution to distinguish from prior art
- During examination, claims are given their broadest reasonable interpretation in light of the specification, so that they may read on by prior art. MPEP2111
- Emphasis: It is not necessary that the prior art
- Suggest the same advantage or result as accomplished by the current invention. MPEP2144
- Expressly suggest the modification or combination; implicit suggestion is allowed. MPEP2144.01
- Non-enabling reference may qualify as §103(a) prior art, but non-enabling reference may not qualify as §102 prior art: obviousness (§103) and anticipation (§102) are different issues.
- Claim interpretation (for §102 and §103 rejections)
