To Our Clients and Friends:
On December 8, 1994, Congress amended United States law to conform to
the General Agreement on Tariffs and Trade (the "GATT Uruguay
Round"). In doing so, they revised key portions of U.S. patent law,
while making less drastic changes to the law of copyrights and
trademarks. This letter will highlight the most significant changes
that may affect our clients in the United States.
Patents May Last Longer
Congress has changed the law to harmonize certain U.S. practices
with international practice. The United States Patent and Trademark
Office ("PTO") currently grants patents for a term of 17 years. The
patent's term begins on the day the patent is issued, regardless of
when the original patent application was filed. The PTO is required
to keep the contents of the application secret from the filing date
of an application to the issue date of the corresponding patent. If
a U.S. patent never issues, the application is never published.
These practices have been criticized as creating a perverse incentive
on patent applicants. Those with inventions in emerging technologies
are said to be encouraged to take steps that would keep their
applications pending until the technology develops and the potential
for profit increases. Some who object to this policy apply the label
"submarine patent" to such long-pending applications. These are said
to remain "submerged" in the PTO while an emerging technology
blossoms, later "surfacing" to surprise an industry.
In contrast, most foreign countries calculate the term of their
patents from the date the application is filed. A typical term is 20
years. In most such countries, the patent is unenforceable until it
is formally granted. So a patent that is pending for two years
before it is granted would be enforceable for a term of 18 years.
Also, many countries publish patent applications at a fixed period
after the filing date, often 18 months, regardless of whether patent
rights are ever granted.
Due to recent international trade agreements, including the GATT
Uruguay Round, the United States will change the term of
enforceability for patents filed after June 7, 1995. The present
term of 17 years from issuance of the patent will no longer apply.
Instead patents will be effective for 20 years from when the earliest
relevant application is filed. To smooth this conversion, Congress
and the PTO have established transitional provisions and regulations
that will benefit holders of some United States patents.
Under the transitional provisions, the term of a certain group of
patents will extend for the longer of two alternative calculations:
17 years from the date the patent issued, or 20 years from the filing
date of the first U.S. patent application upon which the issuing
patent is based. This provision applies to all patent applications
now pending, to all patent applications filed between now and June 7,
1995, and to all issued patents that are in force on June 8, 1995.
Owners of pending or issued patents do not have to file anything with
the government to take advantage of this bonanza. They will get it
automatically. Also, there will be no additional fees. The sequence
of maintenance fees remains unchanged, coming due 3.5 years, 7.5
years and 11.5 years from the date the original patent is granted.
For each new patent application filed on or after June 8, 1995, any
patent that issues will generally expire 20 years from the filing
date. The following shows when a U.S. patent is scheduled to expire.
Calculator of Expiration of U.S. Patents
1. If a U.S. Patent Application is filed by June 7, 1995, and if
the patent issued before June 8, 1978, then the patent expires 17
years from issuance. (1)
2. If a U.S. Patent Application is filed by June 7, 1995, and if
the patent issues after June 7, 1978, then the patent expires the
later of 17 years from issuance, or 20 years from filing of earliest
U.S. parent application. (1) (2)
3. If a U.S. Patent Application is filed after June 7, 1995, then
the patent expires 20 years from filing of application. (1) (2)
Notes: (1) Provided that all maintenance fees are paid. Plus up to 5
more years for marketing delay due to an FDA or Virus-Serum-Toxin
(2) Plus up to 5 more years for successful appeals from the Patent
Examiner and any interference proceeding.
Anticipating the Expiration of a Patent
Congress has included a limitation on the patent term extension in
order to protect businesses that have relied on the "old" patent term
and made reasonable assumptions about the date the patent would
If a competitor starts to commercialize the patented invention or
makes a substantial investment towards commercializing it before June
8, 1995, in anticipation that the patent was about to expire at the
end of a 17-year term, then that business may continue these
otherwise-infringing acts if they pay the patentee an "equitable
remuneration" set by a court. If you are in the process of
developing a product to be launched after someone else's patent
expires, it will be important to take into account the possible
change in its expiration date.
Best of All Worlds: Applications Filed by June 7, 1995
As noted above, Congress created a window of time during which a
patent applicant can get the best of all possible worlds -- or at
least the better of the two alternative patent terms. That is, if a
U.S. patent application is filed before June 8, 1995, when it
eventually issues its term will be the longer of 17 years from date
of issue or 20 years from date of filing. If patent prosecution is
quick, the term during which the patent can be enforced may be longer
than 17 years. But if patent prosecution is slow (perhaps because of
an appeal or an interference proceeding) then the term will not be
diminished from 17 years after the date the patent issues.
If you are at work on any new inventive developments, consider this
window of opportunity to file a patent application that can take
advantage of the special patent term provision. Unless Congress
changes the law enacted December 8, 1994, no patent application filed
after June 7, 1995, will be assured that the patent term will be as
long as 17 years. Moreover, although the new law provides some
amelioration of patent term if there is an appeal or interference,
there is reason to believe that in many instances the term would
still be significantly shorter. For long-lived inventions such as
pharmaceuticals, royalties or revenues received near the end of the
term can be a substantial amount of money. It is anticipated that a
rush of patent applications will be filed shortly before June 8,
1995, in order to take advantage of this special opportunity to "lock
in" a longer patent term by filing a patent application.
Review Your Patent License Agreements
Another result of the new law is that agreements, such as patent
licenses, that extend until a patent expires may now be significantly
affected by the change. Therefore, it would be appropriate to
examine all contracts in which you license patented technology to or
from others with this change in mind.
The first thing to look for is whether royalty or other obligations
extend to a stated date or until a particular patent expires. If
your agreement is written to expire on a stated date, now may be the
time to begin to negotiate new agreements to take into account the
extension of the patent term. In the latter case, the expiration
date of the relevant patent might be affected by the change described
above. If so, the contract may continue for longer than you
Additional Protection against Patent Infringement
In addition, the new law expands the protection a patentee can
receive for patent claims. Formerly, the patentee had the right to
prohibit others from making, from using or from selling the claimed
invention in the United States, and from doing certain other
infringing acts. Effective June 8, 1995, for all U.S. patents, the
law is amended to prohibit others, in addition, from offering to sell
the claimed invention or from importing it into the United States
from abroad. If you suspect others may be infringing your patent,
now would be a good time to evaluate your remedies against them. For
those in the business of importing products, it would be desirable to
evaluate whether any products you import infringe someone else's
Changes to Copyright and Trademark Law
In response to NAFTA and the GATT Uruguay Round, Congress has also
made some changes to U.S. copyright and trademark law, and further
changes are likely in the future. Let us know if you would like to
be advised of them.
