Three Statutory Pillars of Three Statutory Pillars of
PATENTABILITY PATENTABILITY
1. Novelty (new)
2. Inventive Step (non-obvious) (Sec
2(1)(ja))
3. Industrial Applicability (utility) (Sec 2(1)(ac))
Must not be covered by Sec. 3 or Sec.

Patent - PatentabilityPatent - Patentability
An invention can be patented if it is
NOVEL: Must be New, Must DISTINGUISH from “State of the
Art” (PRIOR ART)
Must have INVENTIVE STEPNon-obvious to a person “Skilled in the
Art”
Must have INDUSTRIAL APPLICATIONMust be UsefulMust have Utility
10
InventionInvention
Section 2(1)(j)
“invention” means a new product or
process involving an inventive
step and capable of industrial
application.
Discovery adds to the human knowledge
by disclosing something, not seen
before, whereas,
Invention adds to human
knowledge by suggesting
an act to do which
results in a new product or
new process.
Invention vs. DiscoveryInvention vs. Discovery
NoveltyNovelty
Must not be Anticipated by Prior Publication Prior Claiming Prior Public Use Prior Public Knowledge
The anticipatory disclosure must be entirely contained within a single document (no Mosaicing). If more than one document is cited, each must stand on its own. The cumulative effect of the disclosures cannot be taken into consideration nor can the lack of novelty be established by forming a mosaic of elements taken from several documents. This may be done only when arguing obviousness. (Ammonia's Application, 49 RPC 409).
Inventive StepInventive StepSection 2(1)(ja):
"inventive step" means a feature of
an invention that involves
technical advance as compared to
the existing knowledge or having
economic significance or both
and that makes the invention not
obvious to a person skilled in
the art.14
Non-ObviousNon-Obvious
THE DIFFERENCES BETWEEN THE
CLAIMED INVENTION and the PRIOR ART
are such that the subject matter as a
whole WOULD NOT HAVE BEEN
OBVIOUS at the time the invention was
made to a PERSON SKILLED IN THE ART,
to which the subject matter pertains.

Utility / Industrial ApplicationUtility / Industrial Application
• Be Useful
• Must work / be workable
• At least one recognized,
verifiable and practical end-use
16
Test of Utility: Whether the invention will work and whether it will do what is claimed for it.
