to do an In-depth Patent Search at Home
onto the internet and go to www.uspto.gov.
This should bring up the web page for the Patents and Trademarks office.
Once you are on the page look to the left side of the page and click
On the next page scroll down to Guides,
click on Guidance Tools & Manuals.
Under Tools & Manuals you will see Classification.
Under that you will click on Manual of Patent
The next page will be a page that you will return to once you have retrieved
your Subclass list. You get this list by clicking Documents
and Reports Related to the Manual of Classification located under
the Submit box.
The next page will have a couple of lists. Go to the bottom of the second
one and click on the preference that you want your list. (I suggest
Alphabetical order). Once you print out this 14 Page list then you will
have it for all future reference.
You will need to go back to the page where you enter the Class number
for your item.( That is the number beside your category choice). If
you click on the P that is in the red block beside the number, that
will show you Patents that pertain to this subject. It would be better
to define your search first by submitting the Class number and then
checking out the Patents once you have broken down the category a bit
by finding the Sub Class number.
is a scenario to help you better understand.
For example, if you put the number 5 in the smaller box (Class Number)
you will get a listing for all types of Beds. Find keywords on these
categories that pertain to your product. Click on the Sub Class (black)
number beside them and you will have broken down the search to mostly
the information that you need. Say you are looking to see Cribs, click
on 93.1 and it will bring up massive amounts of information on Cribs
and related items.
Once you find specific information, click on the red P and you will
see the Patents that pertain to this category.
Click on a Patent and if you need to see prior art then go to the top
of the page and click on IMAGES. This should bring up the drawings of
the item so you can compare.
This will conclude your patent search steps.
