||Patent Alert sends out postings once a day. Each posting usually
includes patents that have been issued since the last update.
For weekly subscriptions it is last 7 days, and so on. There is an
option to enable a subscription to deliver 'past' patents. In this
case, it delivers older patents if there are no new ones.
|How do I specify
I would like to be alerted to?
Free accounts. You can choose from dozens of Patent Alert
topics, such as Aeronautics, Internet, and others.
Expert service. You can select patents by company name,
patent class, keyword, country, and several other options. Patent
Alert uses queries consisting of one or more fields, connected with
Boolean Not, And and Or operators. Field code designates an attribute
such as inventor name, assignee (company), patent title, international
or U.S. classification, and other. For example, 'an/Boeing' query
represents patents granted to Boeing company. For the list of all
fields, click on the Search link below.
|How much patent information
can I receive per posting?
Current server capacities allow to include
up to 21 patents into a posting per subscription. This limitation
may be removed in the future.
|I would like to receive
multiple predefined subscriptions in one custom subscription.
||This option is not currently available. One possible workaround
is to create a folder in your e-mail program to receive all mail that
comes from Patent Alert. Popular mail programs allow for this with
features like 'message rules'.
|I am interested in
X patents. I could not find the above category.
||Use the following links:
to find the class and subclass for the patents you need. Also,
if you know some patents from this field, it must be easy to determine
their class and subclass and start from there. Make a search
by patent title and/or keywords, and look at the class information
of the found documents. Then, enter the found class or classes into
a query of a custom subscription.
| Do you have archives
for X patents?
||We don't maintain an online archive of patent data, but you can
always use the Search page to look for specific patents.
|I'm wondering if
you have available the links between patents and cases?
||Every Patent Alert posting comes with a 'Document online' hyperlink.
It will bring you to the USPTO web page that has full text of the
patent, along with the hyperlinks to referenced patents, images, and
more. There is also 'Referenced by' link at the same page, which is
useful for finding about references to the patent.
