Capturing the attention of the global plastics and glass industries, Sekisui Chemical recently filed a lawsuit concerning its Polyvinyl Butyral (PVB) interlayer patent against Kuraray in Europe and Korea.
We know how crucial such cases are for both companies and industries. With extensive expertise, we have assisted international clients in navigating these complex issues for years.

Why Sekisui Chemical Filed the Lawsuit?
Before we talk about why the Sekisui Group started this legal battle against Kuraray, you have to know what is the PVB interlayer that is being the center of this controversy.
PVB interlayer is a versatile material used in laminated glass, created by bonding two glass panes with a thin film of polyvinyl butyral. This interlayer provides essential benefits, such as shatter resistance, UV protection, sound insulation, and improved energy efficiency.
Widely utilized in industries such as automotive and construction, PVB interlayer ensures safety, durability, and comfort in applications ranging from car windshields to architectural glazing.
For example, Sekisui Chemical‘s S-LEC™ film combines safety features with advanced acoustic and solar control technologies. These qualities make PVB interlayers indispensable in safety-critical and aesthetically demanding industries. Here are examples of their products:
- S-LEC™ Sound and Solar Film: Combines noise reduction and solar control.
- S-LEC™ Acoustic Film: Minimizes vibrations and enhances quietness in vehicles and buildings.
Meanwhile, Kuraray is another sector competitor producing competitive PVB interlayers, particularly the Trosifol® The Wedge Acoustic range. These products provide comparable safety features and sound insulation. Likewise, UV protection and glare reduction abound in their Trosifol® The Wedge Acoustic Shadeband line.
The overlapping product features of both companies have resulted in claims of infringement by Sekisui Chemical, as Kuraray’s goods supposedly copy unique characteristics protected by Sekisui’s patents. This is the reason they brought a lawsuit.
Specifically, the lawsuit targets both Kuraray Europe GmbH and Kuraray Korea Ltd., alleging that Kuraray’s products infringe on Sekisui’s European and Korean patents. These patents cover innovations like sound insulation and shrinkage properties of PVB interlayers.
By filing in prominent courts, including Germany’s Munich and Mannheim District Courts and the Seoul Central District Court in Korea, Sekisui seeks injunctions to halt the manufacture and sale of Kuraray’s Trosifol products and claim damages.
The Impact of the Lawsuit on Sekisui Chemical
Of course, we still don’t know what the results of this lawsuit would be. If it is successful, of course, it will bring a positive impact on Sekisui Group. But what are the potential effects to the whole chemical industry? Let’s explore them:
Potential Consequences for the Company
For Sekisui, a positive outcome may confirm its dominance in the PVB interlayer market. Winning the action would confirm the claims and maybe limit Kuraray’s capacity to enter the impacted markets. Higher revenues for Sekisui’s S-LECTM products and more market share might also follow from this.
Litigation is, on the negative side, a time-consuming and expensive procedure. Legal fight expenditures might take focus away from other strategic objectives such as market growth or product development. Furthermore, negative publicity of the issue might affect consumers’ confidence in both Sekisui and Kuraray.
How This Could Affect the Industry?
In a broader context, the case emphasizes the significance of intellectual property in promoting innovation and ensuring fair competition.
If Sekisui wins, the PVB interlayer market may witness more stringent implementation of patent regulations, encouraging manufacturers to increase R&D efforts in order to build really unique solutions.
On the other hand, if Kuraray effectively defends its case, it might indicate that certain PVB interlayer characteristics are too widespread to be covered by patent law. This might lead to a more competitive market, but it could also discourage smaller businesses from funding innovative technology out of concern about legal conflicts.
Meanwhile, for end-users, the case may lead to higher costs or limited options in the short term. Stronger patent enforcement, however, might eventually help customers by guaranteeing better goods and encouraging actual innovation.
Why Protecting Patents is Crucial for Companies
Chemical patents are legal protections provided to innovators for their novel chemical substances, formulations, or techniques.
Patents are important for chemical firms because they enable them to realize the benefits of their research and development efforts. Without adequate protection, rivals might imitate and sell inventions developed after years of research, weakening the original inventor’s market position and income.
For example, Sekisui Chemical‘s ongoing litigation against Kuraray illustrates how intellectual property rights considered to be violated could cause patent conflicts.
Beyond financial security, patents also encourage innovation. Patented rights guarantee exclusive rights, which drives businesses to commit in innovative research. This helps each company individually as well as advances many other sectors.
Furthermore, encouraging fair competition is patent protection. It guarantees that original producers are rewarded in the market and discourages unethical behavior such as reverse-engineering or cloning of things. As the case of Sekisui vs. Kuraray shows, protecting intellectual property also helps a business keep its reputation for quality and innovation.
How This Lawsuit Could Shape Future Patent Cases?
As the case unfolds, it will likely serve as a benchmark for future patent disputes in the PVB interlayer market and beyond. A favorable ruling for Sekisui might encourage stricter enforcement of patents worldwide, particularly in high-tech fields like chemicals and materials.
Conversely, if Kuraray successfully defends its position, it might prompt companies to refine their strategies for patent filing and litigation. Either way, the case is likely to be closely watched as a benchmark for patent law in the chemical and materials industry.
So, what’s the verdict? The key is that, in every sector, including chemical businesses like Sekisui Chemical, maintaining development and competitiveness depends on protecting your innovations.
