How to create a Patent Landscape Search Strategy

Patent Landscape or State-of-Art is a study, as the name suggests is a study which aims to give a single platform overview of a particular field providing multiple insights to decision takers. In simple words, a patent landscape uses a large set of patents to extract relevant information useful for understanding a particular field and all of which is viewable in a single file or a dashboard.

How to create a Patent Landscape Search Strategy

Introduction

Patent landscape study provides an idea about the patent filings related to a specific technology, within a particular geographical area or globally. The patent landscape study begins with building a broad search strategy where you can combine the technology terms with various classifications and you can also add a date-based restriction.

Creating the Patent Landscape Search Strategy

For a landscape project the search terms are kept broad and the analysis set is high in volume. This is done to encompass all possible patent documents related to a cluster of technical areas in a technical field to have a holistic view of each of these clusters in relation to the field or broader technical domain. Often a detailed taxonomy or a categorization list is prepared, which forms benchmark for analysing and categorizing the patent documents obtained in the search with relevance to the scope of the study.

Understanding the Invention

The field of landscape study is ‘Nanotechnology for the treatment of cancer’. The search strategy will involve Nanoparticles, Cancer and Treatment as the keywords and the related synonyms. Here, the main aim is to:

  1. Identify the patents filings that have happened over the last 5 years,
  2. To understand the therapeutic role of nanotechnology – nanoparticles, nanogels, nanosuspensions, gold and silver nanoparticles etc. and
  3. To identify the increase of IP activity related to the major players in this field and
  4. To carry out white space mapping.
Key Terms Synonyms
Cancer Metastasis OR malignant OR malignancy OR tumour OR tumor
Treatment Therapeutic OR therapy OR cure OR treatment
Nanotechnology nano sized particleOR nanoparticle OR nano scaleparticlesOR nanotechnology OR nanosuspension OR nanogels

Identifying Patent Classifications

Following CPC are identified

Relevant CPC Codes Identified
S.No CPC Classification Details
1 A61P35/00  Antineoplastic agents
2 A61P37/00  Drugs for immunological or allergic disorders
3 A61K35/00  Medicinal preparations containing materials or reaction products thereof with undetermined constitution
4 B82Y5/00  Nanobiotechnology or nanomedicine, e.g., protein engineering or drug delivery
5 A61K39/00  Medicinal preparations containing antigens or antibodies

Developing the Patent Landscape Search Strategy

The queries highlighted in bold were used to create an in-depth patent landscape study report, that gives a complete overview about the patenting activity or the innovation. Landscape reports can also be used for policy discussions, strategic research planning or technology transfer.
