Pitch Scientific has the acquired skill of conducting a detailed prior art search and then provide a report specially customized to the end-user. Such reports were well received by the
requesters who have given their appreciation in a number of different ways-
including pleasing words of praise as well as repeating requests for more studies.
Keywords based search for prior art search services in the patents database involves
the appropriate use of keywords and all possible synonyms and representations
of the keywords. An important further
feature of keywords search includes the choice of the text field in which the
keywords are to be searched.
Typical patent contents include the front page, the description or
specification and claims. Frontpage
include several vital information such as publication number, dates including
filing date, publication date, and grant date, along with inventors and
assignee/ applicant’s name, abstract, and often a typical drawing that is
considered illustrative of the invention.
Hence, a typical patent search professional has the option of searching
in any of these fields individually or in combination. The nature of the search being conducted will
largely determine the choice of the fields of search. To be able to make a judicious choice, the
searcher has to understand the role of the various sections of the patent.
Claims are considered to be the heart of a patent, as it is the
enforceable portion against potential threats. The description section, as the name suggests, describes the invention in
greater detail. From a different
perspective, the description section is used by a patent drafter to enable the
claims, which means it is used to define the terms used in the claims, and/or explain
the concepts in detail. Abstract
provides a short description of the distinguishing feature of the invention,
while the title gives a snapshot of the invention.
Therefore, from the aforementioned, it becomes obvious to the searcher
that if one wishes to identify all patients that are enforceable for a given
concept, then the search for the concepts has to be conducted in the claims
section. On the other hand, if the
search is meant to identify all the patents that disclose some features of interest,
then the search has to be extended to all the sections without any
limitation.
Quite often, a search in all sections of the patents can result in a
large number of results that allow for a meaningful analysis. In such situations, one useful technique to
limit the results would be to search within the title, abstract, or claims. The difference in the number of hits when the
field of search is changed from all sections to only claims, title and abstract
can be quite vast, sometimes as much as a 1/3rd drop in the number
of hits. The relevance of the hits also
sometimes improves by limiting to these fields of search.
The flip side of the above situation is that by searching in the title,
abstract, or claims, it is also possible that very relevant results may be
missed out. Depending on the kind of
search conducted, the number of such relevant results could be a few or
many. Regardless of the number of hits,
the simple fact of the matter is that these are relevant hits and in principle,
they cannot be ignored. This means that
a search in the description also needs to be performed.
Hence, the searcher has to be very judicious in choosing or eliminating
search fields for a particular search project.
The trick is to find the balance between getting a few very relevant hits
with the risk of losing out on relevant hits versus sifting through a large
data set enduring several irrelevant hits to identify the most relevant
ones. The ability to find this balance
quickly and efficiently distinguishes the good searcher from the novice in the
field.
