Transaction System Patent, business model field
Project duration: 4 weeks
Client: A major patent law
Type of search: Invalidation search, to uncover
prior art by searching Japanese patent documents to invalidate
an US patent.
Field of Technology: Business
model: transaction system for financial institutions.
Brief Description of the Target Patent
to be Invalidated: The target patent is about an
automatic transaction and payment processing system for
financial institutions such as banks, securities firms,
and trading companies, etc. This patent was filed in 2002,
with corresponding patent family members filed in Europe,
Canada, Japan, China and other countries.
Considering there are no well-defined key word strings to
describe the claimed features of the target patent, we used
mainly classification searches, with full text key word
strings search as a supplemental search.
First search: Using F Term, Japanese patent
unique classification search
5B055CB11 + 5B055CC13 + 5B055MM14 + 5B055MM15
Hits generated from the search: 690
Second search: Using FI code, another Japanese
patent unique classification search
[(G06F15/30@H + G06F17/60,234@Q) - (5B055CB11 + 5B055CC13
+ 5B055MM14 + 5B055MM15)]
Hits generated from the search: 365
Third search: Expanding the search to wider
scope using FT and FI combination
[(2C005HB10+3E040AA05) – (G06F15/30@H + G06F17/60,234@Q
+ 5B055CB11 + 5B055CC13 + 5B055MM14 + 5B055MM15)
Hits generated from the search: 889
Fourth search: Using full text search in Japanese
Hits generated from the search: 642
Database used: NRI, PATOLIS (for classification search),
and IPDL (for downloading full patents for review.
5 Japanese patent documents are submitted to the
client for a further review. Out of the 5 documents, one
patent is considered to be a document of relevance, which
means the claimed invention of the target patent cannot
be considered non-obviousness when the document is combined
with one or more other documents, such combination being
obvious to a person skilled in the art.
