实施的话，正常情况没有限制；转让或处分权利的时候应该有一定的限制吧，即只能处分自己的那部分权利。

35 U.S.C. 262 Joint owners.
In the absence of any agreement to the contrary, each of the joint owners of a patent may make, use, offer to sell, or sell the patented invention within the United States, or import the patented invention into the United States, without the consent of and without accounting to the other owners.
MPEP 301 Ownership/Assignability of Patents and Applications [R-3]
IV. < INDIVIDUAL AND JOINT OWNERSHIP
... ...
Joint ownership -
... ...
Each individual inventor may only assign the interest he or she holds; thus, assignment by one joint inventor renders the assignee a partial assignee. A partial assignee likewise may only assign the interest it holds; thus, assignment by a partial assignee renders a subsequent assignee a partial assignee. All parties having any portion of the ownership in the patent property must act together as a composite entity in patent matters before the Office. |
