Patents
Kapro's innovative hand tool designs have changed the face of the modern layout tools and measuring tools industry. Our portfolio of intellectual property is constantly expanding, and all of our new products have patent-protected designs and features.
Our patent-protected features on aluminum levels, construction tools and carpentry tools include the Plumb Site® Dual-View™ vial, Postrite® Post Level, Magnetic Lock Combination Square, Sure Grip Chalk Line & Level, and Set & Match® Ruler.
Some of Kapro's most important products are brought to market under trademarks that have gained recognition, and increasing consumer awareness. Our in-house legal department has its own intellectual property section, headed by a patent attorney.
As a leading hand tool innovator, we recognize and respect all third-party IP rights, and attach great importance to our own rights, which we defend aggressively.
Kapro has been at the forefront of the fight against product piracy in our industry, and continues to lead the way in innovation and invention.
