Is a laser level patented?
Short answer: specific designs of a laser level have been patented many times, but "a laser level" as a general idea is not what is protected. What matters is the exact combination of features in your version.
What our index shows
- 349 US and WO patent publications since 2000 have a title matching “laser level” or a close variant (our index of 9.7 million patent families; one publication per family).
- Among the 290 best keyword matches we examined, 116 were published in 2020 or later, and the earliest was published in 2000.
- Most frequent assignees in those matches: STANLEY BLACK & DECKER INC (21), BOSCH GMBH ROBERT (19), MILWAUKEE ELECTRIC TOOL CORP (16), BLACK & DECKER INC (8).
- Most common patent classes (CPC subclasses): G01C (201), A61N (38), H01S (27), Y10S (24).
Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.
