dependant claims

Posted by Anonymous . updated on 2/26/2009
Hey all,

I've discovered a new method, with three distinct enough variations to allow for three independant claims.

now using any one of these new or any existing methods, i've come up with further improvements.

i could claim each method and then each of the improvements, but that will use a lot of claims, and additionally wont cover those improvements using existing methods.

is there an easy way to represent that those further improvements as being dependant on all methods having the same end result?

Thanks for taking the time to read this and even more if you can help.

If your new improvements do not require your old improvements to build upon, they may be seen as a separate invention that will be restricted out if you put it is the same application.  If your second set of inventions was an improved way to make a milk shake that doesn't depend upon how the basic milkshake is made, you might have:

A method of making a smooth milkshake comprising the actions of:
1. first do X,
2. make a milk shake (any old or new way),
3. then do y.

I think what the OP is asking about is multiple-dependent claims.

4.  The method of Claim 1, 2, or 3 further comprising:
poking the stick in your eye.

In most of the world, they are preferred.  Here, in the US, they are frowned upon.

Regards.

so essentially, i should apply for a separate patent?
if i am going for an american patent?


4.  The method of Claim 1, 2, or 3 (or any other method), further comprising:
removing said stick

is what i want to say...

How is that any different from the following?

4. A method comprising:
removing a stick.

If that's your claim, file a new application.

Regards.
