Are you violating patent laws
in your basement? Patent laws have changed since this article was published in 1966,
but the tenets are basically the same - do your due diligence on prior work assignment
before publishing any publicly accessible product (print or physical). Since part of
Popular Electronics' raison d'être is to provide circuits for hobbyists to build
and benefit from, the lawyer who wrote this piece focuses on such applications. He claims,
at least according to 1960 patent law, "There are court decisions which hold that experimental
use of a patented invention for the sole purpose of gratifying curiosity or a philosophical
taste, or for mere amusement, is not an infringement." HOWEVER, before you conclude that
this must still be the case, read this synopsis from the Ius Mentis website titled "Crash Course
on Patents," wherein is stated, "In most European countries, the exclusive exploitation
rights granted by a patent are restricted to commercial exploitation. A private person
who builds the patented invention in his own home for his own personal goals cannot infringe
on a patent... U.S. law is more strict. It forbids anyone from making, using or selling
the invention, even when the use is strictly personal." I'm not a lawyer, and I
don't play one on TV, but my unsolicited advice is to be real sure of your legal standing
before going public with any work be it electrical, mechanical, chemical, etc. The bank
account you save might be your own.
Infringers Beware
By Thomas F. Kirby
Most electronics experimenters are aware that almost every circuit diagram or construction
project published in Popular Electronics has - in some form - been patented. And, as
electronics technology becomes more complex and/or sophisticated, the chances of and
opportunities for patent infringement are that much greater. Construction projects utilizing
the most modern components are always built around existing patents.
The following article was prepared for Popular Electronics by a Registered Patent
Attorney. It explores some patent problems that could arise from building electronic
projects published in this magazine and any of the other electronics magazines, as well
as various handbooks.
Unlike a patent, which is a "negative right" (it excludes others from making or using).
this article looks at the positive side of things and states that experimenters CAN build
projects for their own enjoyment.
- The Editor
Many currently available transistor and tube handbooks and other manuals containing
electronic circuit diagrams contain a warning similar to the following: The electronic
devices and circuits disclosed herein may be covered by patents of the John Doe Company
or others. The disclosure of information herein does not grant a license under any patents
covering such electronic devices, such circuits or combinations of such electronic devices
with other devices or other circuit elements.
Some readers may have never noticed this warning, others blithely ignore it, and some
may not fully understand it. Therefore, a brief discussion of such warnings should be
of interest-and could save someone money!
The Patent Owner. Many publishers of literature disclosing circuit
diagrams are in the business of manufacturing and selling components such as transistors,
tubes, and other basic electronic devices. Frequently, they also manufacture equipment
using these components in various combinations and circuit arrangements.
Since these manufacturers want to sell their components and equipment to the widest
possible market, they need to publish information about the components and how they can
be used. Very often, the components themselves and many of the circuits in which they
are used are patented or are the subject of pending patent applications. These patents
(and applications) might be owned by the manufacturer, or by another firm from which
the manufacturer has a license. Or, in some cases, the patents might even be owned by
an independent party who has discovered or invented new ways of using the components.
In any event, the manufacturer-publisher wants it clearly understood that just because
the information is published, it does not follow that the reader is free to exploit this
information commercially. The patent owner still intends to benefit from his patent rights
and may require a user of any patented invention to take a license.
Patent Laws. The United States patent laws are very strict. Whoever
owns a valid patent has the right to exclude others from making, using or selling apparatus
embodying the invention covered by any claim of that patent. Therefore, whoever without
authority makes, uses or sells any patented invention, within the United States during
the term of the patent, infringes the patent.1
In a patent infringement lawsuit, the court can award damages adequate to compensate
for the infringement "but in no event less than a reasonable royalty for the use made
of the invention by the infringer, together with interests and costs as fixed by the
court." In some instances, the court may increase the damages up to three times the amount
found or assessed."
Faced with these stringent laws, what risk is there in building circuits disclosed
in publications? It depends to some extent on the purpose for which the circuit is being
built.
The Electronics Hobbyist. It is common knowledge that electronics
experimenters and hobbyists are continually building circuits they find in publications.
Frequently, many of these circuits are patented. As a practical matter, it is impossible
for a patent owner to know which hobbyists and experimenters are actually infringing
his patents.
Fortunately, however, the position of experimenters and hobbyists rests on sounder
legal ground. There are court decisions which hold that experimental use of a patented
invention for the sole purpose of gratifying curiosity or a philosophical taste, or for
mere amusement, is not an infringement.
But this rule cannot be invoked to protect persons (or companies) who use a patented
invention commercially, as in the course of business or for profit. Commercial use of
patented inventions of others invites a charge of patent infringement. This is true even
though the publication from which the particular circuit was obtained did not contain
a notice that the circuits disclosed therein might be patented.
Most companies are very careful to police and enforce their patents - against the
small operator as well as the larger competitor. This is sound and necessary business
practice. The patent owner can require an infringer to stop manufacture, use, or sale
of infringing equipment, or he can require the infringer to take a license and pay a
royalty. Having to stop manufacture and sale of apparatus could be costly or even ruinous
to a small operator. Taking a license, even at a reasonable royalty rate, is another
cost item on a product which could create problems if not considered in advance.
Minimizing Infringement Risk. It is wise to have a patent search
made before getting into production on apparatus employing electronic circuitry to see
if there are any "live" patents covering the proposed circuitry. If no such patents are
found, the risk is minimized. (Note: There is always the possibility that a pertinent
patent was not found in the search or that a patent was issued after the search was made.)
If patents are found which might be infringed, you have a chance to consider the desirability
of some sort of license arrangement with the patent owner, or run the risk of a charge
of patent infringement action.
Only a few high points on the subject of patent infringement are covered here. If
you have any doubts about incurring liability for patent infringement through the use
of circuits found in publications for commercial exploitation, the sensible thing to
do is consult a patent attorney, before you make a big investment.
