Type of Patent Searches & Analysis
• Patent Map / Landscape (Technology Trend Analysis / Competitor Analysis)– From macroscopic perspective, analyzing patent set related to specific technology
– Japanese customers like to call this services “Patent Map / Patent Mapping”
• Patent Collection Search– Collecting patents related to company’s R&D theme
• Pre‐Filing Search (Prior Art Search / Patentability Search)– Search conducted before filing patents or request for examination. In general, 100~300 documents are
totally reviewed
• Invalidity Search / Prior Art Search– Search for invalidating competitors’ grant patents / preventing competitors’ published applications from
being granted by patent offices
• Clearance Search / FTO Search * FTO = Freedom To Operate– Confirm whether companies’ products or services infringe others’ patents or not before they are launched
into the market
• Patent Evaluation– Evaluating patent value from non‐economical perspective for making decisions whether keep or abandon

Overview of Patent Classifications
23
• Patent classification schemes are used to organize and index the technical content of patent specifications so that specifications on a specific topic or in a given area of technology can be identified easily and accurately.
• The most important classification is IPC, but recently CPC (Cooperative Patent Classifications) used by USPTO and EPO has become more important classifications for searching patent documents especially in English
IPC
Reference : IPC Section(CPC section is the same as IPC except for Y)
• SECTION A —HUMAN NECESSITIES
• SECTION B — PERFORMING OPERATIONS; TRANSPORTING
• SECTION C — CHEMISTRY; METALLURGY
• SECTION D — TEXTILES; PAPER
• SECTION E — FIXED CONSTRUCTIONS
• SECTION F —MECHANICAL ENGINEERING; LIGHTING; HEATING; WEAPONS; BLASTING
• SECTION G — PHYSICS
• SECTION H — ELECTRICITY
• SECTION Y ‐ GENERAL TAGGING OF NEW TECHNOLOGICAL DEVELOPMENTS; GENERAL TAGGING OF
CROSS‐SECTIONAL TECHNOLOGIES SPANNING OVER SEVERAL SECTIONS OF THE IPC; TECHNICAL
SUBJECTS COVERED BY FORMER USPC CROSS‐REFERENCE ART COLLECTIONS [XRACs] AND DIGESTS

• CPC (Cooperative Patent Classification) is a patent classification system, which has been jointly developed by EPO and USPTO. The CPC is substantially based on the previous ECLA (European classification system), which itself was a more specific and detailed version of the International Patent Classification (IPC) system.
• FI (File Index) and F‐term (File forming term) are Japanese patent classification systems consisting of approx. 190,000 and 360,000 entries respectively, which enable the efficient search of patent documents. It is also noted that FI is based on IPC.

• Pattern 1 – Only keywords combination– Easy to understand but might hit many noise documents (irrelevant
documents)• Example ‐ diesel AND (particulate or soot) AND filter AND Pt
• Pattern 2 – Only classification combination– Good to locate highly relevant documents but possible not to locate
important documents • Example ‐ F01N3/022 AND (B01J23/40 OR B01J23/42)
• Pattern 3 – Combination between keywords and classifications– Most reasonable search query to locate relevant documents
• Example ‐ (F01N3/022 AND Pt) OR ((diesel AND (particulate or soot) ANDfilter) AND (B01J23/40 OR B01J23/42))

– In this lecture, please do not change this collection
• Publication number– If you put only Country Code (such as
WO) in Publication Number line, you can limit published country
– Of course, you can locate a specific patent document when inputting patent number (publication number / grant number)
• Publication date– If you’d like to search patents published
during specific years (e.g. 2000~2010), please input 2000‐2010

Reference : Applicants/Assignee search
• Basically Applicants/Assignees of each patent documents were recorded when they were published, and not changed if Applicants/Assignees would be acquired / name‐changed.
• Important points in searching patents filed by specific Applicants/Assignees are– Checking former company name– Checking company history (name
change, consolidation etc)– Checking M&A

Exercise & Group WorkSimple Patent Analysis using Patentscope
Patent Mapping / Patent Landscape(see reference : Graphene: The worldwide patent landscape 2015)
• A company must research technology trend comprehensively analyze the trend in a specific technological field in order to develop its R&D strategy and to choose an R&D subject.
• Such research usually covers more than 1,000 patents, and may have to cover more than 10,000 patents in some technological fields. Some examples of research documents made publicly available include the Report of Patent Application Technological Trend Research , an annual report published by the Japan Patent Office, and the WIPO Patent Landscape Reports (PLRs) published by the World Intellectual Property Organization. Once the research subject is determined, technological information research is conducted to gather and sort information on past technologies that are similar to the chosen subject.
