Intellectual Property | Know-how

Patents protect the owner's right to prevent others from profiting  by his invention and are subject to litigation.  Other forms of legal protection are copyrights and trademarks.   Copyright, another form of intellectual property law, protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture. Copyright does not protect facts, ideas, systems, or methods of operation, although it may protect the way these things are expressed.  Trade secrets such as the Coca Cola recipe are never published in literature or in a patent.


The first U.S. mower patent was awarded in 1868
to Amariah Hills of Connecticut.   Early Connecticut manufacturers of lawn-mowers were located in Glastonbury, Hartford, Derby and New Britain.   You can see an OCR of the original patent drawing  - it is linked to the record below.  Click on the image to enloarge the technical drawing.


Patent drawings and technical descriptions are available for all lawn mowers and small engines. Most people don't realize that patent drawings are not trade secrets and many US patents are publicly available in Europe 12-18 months before they are published in the United States.  The inventor or assignee pays a filing and yearly fee to the USPTO to register his invention. This protect the inventor or assignee before literature such as journal articles or or other technical literature is published.
