An engineering team is often confident that it knows its field thoroughly: it reads specialized journals, follows competitors, and attends conferences. But personal outlook is not the same as a systematic picture of the world state of the art. Patent databases contain solutions that were never published in the open press, never exhibited at trade shows, and never discussed at conferences — simply because patenting and scientific publication serve different purposes, and far from every company wants to talk about its development before it has obtained a protection document for it.
Patent research of the state of the art is a way to close this gap: to obtain an objective, documented picture of what has already been done in the world and to compare your own development against this background.
In this article, we will examine what such a study shows, which methods are used for it, how the conclusions are documented, and how to use the results in an R&D project.
What Patent Research of the State of the Art Shows
A state-of-the-art study answers a question that is rarely possible to close with the team’s internal expertise alone: what place the solution under development occupies among existing technical solutions in this field, regardless of where they are patented — in Russia, Europe, the USA, China, or Japan.
The result of such a study is several interrelated pictures. First, the patent landscape — a map of who patents solutions in the area of interest and to what extent, which companies and countries lead, and how patents are distributed across specific technical areas within the overall topic. Second, a list of the closest analogues — specific patents and applications that solve the same or a similar technical problem in the same or a similar way. Third, a comparison of your own solution with these analogues by essential technical features, which makes it possible to answer the main question: does the development have a real difference from the state of the art, or does it repeat already known approaches.
It is important to understand the difference between a state-of-the-art study and an ordinary novelty patent search. A novelty search is usually limited to a narrow task — to check whether a specific patent claim can be patented. A state-of-the-art study is broader: it covers the entire technology field, shows the dynamics of its development, and helps to understand not only “is the solution patentable” but also “in which direction is the industry moving overall” and “does it make sense to invest in this particular approach”.
Which Patent Research Methods Are Used to Compare Technologies
To obtain a full picture of the state of the art, patent research methods are usually applied not separately but in combination — each covers its own part of the task. The classical methodology includes selecting patent information on the topic, systematizing it, and three areas of analysis: comparing technical characteristics, studying the dynamics of the field’s development, and assessing the activity of specific market players.
Analysis of the Technical Characteristics of Analogues
The first and most substantive stage is comparing the technical characteristics of your own development with the parameters stated in analogue patents. Here the work is done not with general descriptions but with specific features: materials, ranges of values, structural solutions, and ways of implementing a function.
In practice, such a comparison is presented as a table in which the rows contain the essential features of the solution and the columns contain your own development and the analogues found. This makes it possible to see clearly which features coincide fully, which partially, and which are actually absent in the known solutions. This table subsequently becomes the basis for the patent claim, if the development turns out to be patentable, and for formulating competitive advantages, if it is a matter of bringing the product to market.
Analysis of Technology Development Trends
Patent research of technology development trends shows not a static snapshot of the field but its movement over time: how the number of patent applications changed by year, which technical approaches gained popularity, and which were gradually displaced by more efficient solutions.
Such analysis is based on grouping the patent array by filing year and by technical areas within the topic. Growth in the number of applications in a particular area usually signals that the industry considers it promising and invests in its development. A decline in activity, on the contrary, may indicate that the approach has exhausted its potential or has been displaced by an alternative technology. For a team choosing a development direction, this picture is no less important than the list of specific analogues: it shows whether the future technology is moving in line with the general trend or is trying to develop a direction that the industry has in effect already left behind.
Analysis of Companies’ Patent Activity
The third area is studying the patenting dynamics of specific companies and scientific organizations working in this field. Here the study answers the questions: which market players patent the most solutions on this topic, how their patents are distributed by country, which companies are only starting to enter this area, and which have long held leading positions in it.
Analysis of patent activity helps not only to assess the competitive environment but also to forecast where exactly the key players are heading. If a large company has sharply increased the number of applications in a narrow technical sub-area, this often means it is preparing to bring a new product or technology to market — and this should be taken into account when planning your own development.
How to Document the Study’s Conclusions
The results of patent research of the state of the art are recorded in a document — not as scattered notes but in a structure that allows the conclusions to be used in project work, in preparing a patent application, and in defending the results before a customer or investor.
A typical report structure includes:
- the purpose and objectives of the study, the object and subject of analysis;
- a list of the sources of patent information used — databases, classification headings, search depth by year;
- a list of the analogues identified, indicating patent numbers, countries of issue, and patent holders;
- a comparative table of the technical characteristics of your own solution and the analogues;
- a description of the identified technology development trends — the dynamics of patenting by year and by area;
- an analysis of the patent activity of key companies in the field under study;
- final conclusions: how the development differs from the state of the art, whether there are risks of conflict with others’ valid patents, and which directions of technology development look the most promising.
Such a report is prepared in accordance with the requirements of GOST R 15.011-96 if the study is carried out as part of an official R&D project or a government contract. But even without formal requirements, a structured report is useful in itself: it turns the team’s intuitive ideas about the industry into a documented picture on which decisions can be based.
How to Use the Results for R&D
A state-of-the-art study is useful only when its conclusions are returned to the project, rather than remaining a document “for reporting purposes”. In practice, the results are used in at least three points of a project.
First, at the task-setting stage — the identified analogues and technology development trends help adjust the terms of reference so that the development initially moves in a direction where there is real room for novelty rather than repeating an already known approach. Second, at the design stage — the comparative table of technical characteristics suggests which specific features of the solution should be strengthened or changed so that the difference from analogues is substantial and provable. Third, at the stage of preparing a patent application — the study data become the basis of the patent claim and make it possible to assess in advance whether the application will withstand examination.
A separate practical value lies in risk reduction. If the study shows that the direction of interest is densely occupied by the valid patents of several large players, the team still has time to adjust course before the main resources have been invested in development, rather than after a prototype has been made.
How “POSINT” Automates State-of-the-Art Analysis
A full state-of-the-art study means working with thousands of patent documents in different languages, systematizing them by year, area, and patent holder, and then manually comparing technical features with your own development. Done manually, patent information and patent research of this volume take a specialist weeks: you need to formulate search queries for different patent classifications, review hundreds of documents, and fill in comparative tables by hand.
The “POSINT” AI engineer takes over the main part of this work:
- converts a development description in natural language into correct search queries for patent databases, including foreign ones;
- finds relevant analogues and groups them by technical areas within the topic;
- builds the dynamics of patenting by year and patent holder, showing technology development trends;
- generates a comparison of the technical characteristics of your own solution with the analogues found;
- compiles a structured report that can be used as the basis for an official report under GOST or as working material for the team.
This shortens the preparation time of a state-of-the-art study from weeks of manual work to hours and gives the team a documented picture of the industry even before the main R&D resources have been invested in the project. Conduct a patent search with “POSINT” before starting development — it is faster than manual analysis and will show the real place of your technology among world analogues.
Conclusion
Patent research of the state of the art makes it possible to look at a development not from inside the team but in the context of the entire industry. It shows which solutions already exist, which technical approaches competitors use, how technology development trends are changing, and how much your own development really differs from the world state of the art.
For R&D this is especially important at an early stage. The sooner the team identifies the closest analogues, valid patents, and saturated areas, the lower the risk of spending time and budget on a solution that is already known or has weak potential for further legal protection. The results of such a study can be used when adjusting the terms of reference, choosing the development direction, forming technical advantages, and preparing a patent application.
At the same time, the value of patent research is determined not by the number of documents found but by the quality of their analysis. A systematic comparison of technical characteristics, development trends, and patent activity turns an array of patent information into a practical tool for making engineering and management decisions.
Conduct a state-of-the-art study with “POSINT” before the main resources are invested in development — and make decisions based on patent data, not assumptions. Submit a request — and get an objective picture of the state of the art before the main resources are invested in the project.
