This is to inform you that, from 29th November 2000,
patent applications filed in the United States will be published
18 months after their first filing date (priority date).
Previously patent applications in the United States were published
only if and when they were issued, that is, after approximately
2-3 years.
During this period it was not possible to obtain any information;
when a US patent application was not issued, everything remained
secret.
This typically US norm did not allow for a full view of the technique
and patent situation of competitors relating to the United States,
even though it guaranteed total discretion.
The United States Patent and Trademark Office (PTO) has published a regulation which foresees the following exceptions to automatic publication:
All patent applications filed before, but which are still pending
on 29.11.2000 can be published on the specific request of the Patentee
except in the cases of (1) to (5) above.
The content of a patent application will be published as it was
filed; no subsequent amendments to the text after filing will be
published with the application except on the specific request of
the Patentee and with a good reason.
The publication of a US patent application gives the Patentee provisional
rights for the transitional period between the publishing and granting
of the application.
These provisional rights depend on the patent being issued and can
entitle the Patentee to reasonable royalties for infringement of
the claims in the published application during the transitional
period. Such provisional rights are also dependent on the requirement
for the claims in the issued patent to be substantially identical
to those made in the published application.
It is also possible, on the Patentee's specific request, to defer examination of a patent application for a period of up to 3 years from its first filing date (priority date).
