Case Assisted by a Corporate Attorney | Favorable Judgment for a Client in a Manufacturing Technology Patent Dispute

The client who sought the corporate specialist attorney was the head of the research institute of a domestic company that manufactures and sells insulation materials.

Based on technology developed over many years, the company had been entering into continuous supply contracts with domestic construction companies.

A competitor, however, filed a lawsuit seeking an injunction against infringement and damages, alleging that the products of the client’s company infringed the competitor’s patent.

In particular, the competitor demanded that the court order the submission of the product manufacturing process diagrams and experimental data, asserting that it would use these in the expert appraisal procedure.

The client was concerned about the leakage of technology, given that the manufacturing process in question was the company’s core trade secret.

To respond to this, the client requested the assistance of a corporate specialist attorney with extensive experience in patent trials and infringement litigation.

Article 133 of the Patent Act provides that, where a patent does not meet the statutory requirements or there is a defect in the registration process, an interested party or an examiner may request an invalidation trial.

The key to a determination of patent invalidity is the technical distinctiveness and effect as compared with prior art, and the legality of the application and registration procedures.

The main issues in this case were as follows.

In response, the corporate law specialist attorney established a strategy focused on proving the grounds for invalidation of the competitor's patent through technical analysis and verification, while protecting the trade secrets.

The corporate attorney specifically set out the industrial losses and the risk of breach of contract with business partners that could arise if the manufacturing process materials were leaked to a competitor.

The attorney also submitted to the court a written opinion arguing that the scope of the appraisal procedure should be limited and that it should be conducted in closed session, thereby persuading the bench.

As a result, the core technology relating to the manufacturing process was not exposed externally and could be safely protected.

The corporate attorney reviewed domestic and foreign patent databases and academic papers and secured numerous prior-art references similar to the competitor's patent in terms of structure and performance.

Based on the materials secured, the attorney prepared a petition for an invalidation trial and focused on highlighting the point that the patent showed no substantial improvement in performance over existing technology.

Through this, the attorney established a strategy that clearly revealed the lack of novelty and inventive step in the competitor's patent.

The corporate law specialist attorney, in cooperation with an outside materials engineering expert, compared and analyzed the client's technology and the competitor's patent from multiple angles.

In the course of the analysis, the structural differences between the two technologies, their applicability, and their market competitiveness were assessed in detail.

As a result, an expert opinion was secured that the client's technology was clearly distinguished from the competitor's patent in terms of its scope of use and sustainability, and this was submitted to the Intellectual Property Trial and Appeal Board and used as an important ground in the invalidation trial.

A patent dispute is not simply a matter of contesting the existence of a right; it is a complex matter that requires both specialized understanding of the relevant technology and legal judgment.

In particular, to contest the validity of a competitor's patent or to protect trade secrets, analysis of technical characteristics, prior art searches, and strategic responses to adjudication and litigation procedures are indispensable.
