Introduction

The concept of the "IP landscape" (IPL) has been attracting attention recently.

An IP landscape is not limited to patent information, but also integrates and analyzes business information (e.g., non-patent information such as papers, news releases, stock information, and market information). Intellectual-property-based business management is realized through the analysis of intellectual property information applied to the formulation of management strategies and business strategies. This is a comprehensive approach that includes but not limited to planning of open and closed strategies, selecting M&A candidates, searching for alliance partners, and formulating intellectual property strategies, through the exploitation of intellectual property information.

IP landscaping usually includes patent search and patent analysis. In patent search and patent analysis, it is important to grasp the market position of each company and the overall technological trends and development trends for each technology. More specifically, it is important to understand what intellectual property your own company and other companies hold, what the strengths and weaknesses of other companies are, and how other companies are trying to exploit their intellectual property. In other words, it is important to understand both the business strategy and the intellectual property strategy of each company.

同業や競合企業が特許に注力している分野を知ることで、自社の戦略や製品開発の方向性を把握することができます。また、競合企業の特許出願件数の増減傾向を知ることで、競合関係の変化や動向を把握することができます。例えば直近10年間の出願件数の順位と直近3年間の出願件数の順位とを比較することで、順位の上下による業界内でのポジショニングの変動を把握することができます。このような情報をもとに、知財戦略において最も重要な自社の出願戦略を見直すことができます。なお、パテントインテグレーションレポートでは、国内及び主要国の企業や注目技術分野などの出願件数上位1000件までのテーマでレポートを作成しているので、ここに挙がっていない関連する他の企業や技術分野と比較することで、より有益な示唆を得ることもできます。

同業や競合企業の長期的な特許出願件数の推移から、長期トレンドと出願件数の山や谷を確認することができます。これにより、例えば研究開発の活発化傾向・減退化傾向、突発的な開発集中時期等を特定することができ、自社の特許出願や知財戦略に対する見直しを行うことができます。また、競合企業の製品や技術開発の傾向を知ることで、自社の新規開発や商品開発の位置づけを把握することができます。なお、このグラフにおいても直近の期間については未公開の期間が存在する可能性があるために、未公開の期間に出願されると予測される出願件数を補って動向を把握する必要があります。
