NOVELTY AND OTHER CONDITIONS FOR OBTAINING A PATENT
In order for an invention to be patentable it must be new as defined in the
patent law, which provides that an invention cannot be patented if: “(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 application for
patent in the United States . . .”
If the invention has been described in a printed publication anywhere in the
world, or if it has been in public use or on sale in this country before the
date that the applicant made his/her invention, a patent cannot be obtained. If
the invention has been described in a printed publication anywhere, or has been
in public use or on sale in this country more than one year before the date on
which an application for patent is filed in this country, a patent cannot be
obtained. In this connection it is immaterial when the invention was made, or
whether the printed publication or public use was by the inventor
himself/herself or by someone else. If the inventor describes the invention in a
printed publication or uses the invention publicly, or places it on sale, he/she
must apply for a patent before one year has gone by, otherwise any right to a
patent will be lost.
Even if the subject matter sought to be patented is not exactly shown by the
prior art, and involves one or more differences over the most nearly similar
thing already known, a patent may still be refused if the differences would be
obvious. The subject matter sought to be patented must be sufficiently different
from what has been used or described before that it may be said to be nonobvious
to a person having ordinary skill in the area of technology related to the
invention. For example, the substitution of one material for another, or changes
in size, are ordinarily not patentable.
In generic terms: in determining the patentably of your your invention, the
Patent Office must consider utility, novelty, obviousness,
and so called "secondary considerations." Generally, if your product or process
does something useful that a "close" one does not, then your product would
logically be novel. You must then question if the additional features or
functions that you are claiming as novel would have been obvious to do for an
average person skilled in the field of your invention. If the novelty is clearly
not obvious to an average skilled artisan, then your invention would very likely
be patentable, all other things being equal. If your invention's novelty is
questionably obvious, then the fallback argument, although some what weaker, is
to set forth any secondary consideration that relate to the commercial viability
of your product over the others in question. For the more complicated case where
your invention is questionably obvious, read on...
Patent law is designed to serve the small inventor as well as the giant research
organization. One fact to keep in mind is that most, if not all, inventions are
combinations and mostly of old elements. Therefore an examiner may often find
every element of a claimed invention in the prior art. If identification of each
claimed element in the prior art were sufficient to reject patentability of your
invention, then very few patents would ever issue. Patent examiners are not
allowed to reject patents solely by finding your claimed elements in the prior
art. If that were allowed it would permit an examiner to use the claimed
invention itself as a blueprint for piecing together elements in the prior art
to defeat the patentability of patents. The courts have said such an approach
would be an illogical and inappropriate process by which to determine
patentability.
You should also be aware that it is not a requirement of patentability that an
inventor correctly set forth, or even know, how or why the invention works.
Generally, the claimed invention must be considered as a whole, and the question
is whether there is something in the prior art as a whole to suggest the
desirability, and thus the obviousness, of making the combination. When
determining the patentability of a claimed invention which combines two known
elements, the question is whether there is something in the prior art as a whole
to suggest the desirability, and thus the obviousness, of making the
combination.
To prevent the use of hindsight based on the invention (i.e., viewing the
prior-art in terms of what your invention or the art after your filing date
teaches) to defeat patentability of the invention, courts require the examiner
to show a motivation to combine the references that create the case of
obviousness. In other words, the examiner must show reasons that the skilled
artisan, confronted with the same problems as the inventor and with no knowledge
of the claimed invention, would select the elements from the cited prior art
references for combination in the manner claimed.
Courts have identified three possible sources for a motivation to combine
references: the nature of the problem to be solved, the teachings of the prior
art, and the knowledge of persons of ordinary skill in the art. It is not
allowed for the examiner to just rely on the high level of skill in the art to
overcome the differences between the claimed invention and the selected elements
in the references, and provide the necessary motivation.
Instead, the examiner, if rejecting your claim based on obviousness, must
explain what specific understanding or technological principle within the
knowledge of one of ordinary skill in the art would have suggested the
combination. Otherwise, if a rote piecing together of prior-art elements could
suffice to supply a motivation to combine, the more sophisticated scientific
fields would rarely, if ever, experience a patentable technical advance. That
is, for example, in complex scientific fields, the examiner could routinely
identify the prior art elements in an application, invoke the lofty level of
skill, and rest its case for rejection. To counter this potential weakness in
the obviousness construct, the suggestion to combine requirement stands as a
critical safeguard against hindsight analysis and rote application of the legal
test for obviousness.
Obviousness is ultimately a question of law that rests on underlying factual
inquiries including: (1) the scope and content of the prior art; (2) the level
of ordinary skill in the art; (3) the differences between the claimed invention
and the prior art; and (4) objective considerations of nonobviousness. Objective
considerations such as failure by others to solve the problem and copying may
often be the strongest evidence of nonobviousness.
This objective evidence of nonobviousness includes so-called "secondary
considerations" such as copying, long felt but unsolved need, failure of others,
commercial success, unexpected results created by the claimed invention,
unexpected properties of the claimed invention, licenses showing industry
respect for the invention, and skepticism of skilled artisans before the
invention
The so-called "secondary considerations" provide evidence of how the patented
device is viewed by the interested public: not the inventor, but persons
concerned with the product in the objective arena of the marketplace.
