05-74891 3D Systems, Inc. v. Envisiontec, Inc., et al

EXHIBIT E

DISPUTED TERM(S) `981 Patent - Claim 11 Limitation 5 "data representing the three dimensional object" `537 Patent - Claim 81 Limitation 10 "means for sweeping the applicator across at least a portion of at least some of the previously formed object cross-sections"

COURT'S CONSTRUCTION providing data representing adjacent cross sectional layers of the three dimensional object to be found which was generated on CAD system This is a means plus function limitation. The function is: sweeping the applicator across at least a portion of at least some of the previously formed object cross-sections The structure called for is: a "motor-driven threaded drive shaft" as described in the `931 patent

`981 Patent - Claim 11 Limitation 7 "exposing" `981 Patent - Claim 11 Limitation 8 "layer" `981 Patent - Claim 11 Limitation 10 "forming and adhering successive cross-sectional layers of structure"

Doc. 98 Att. 5

05-74891 3D Systems, Inc. v. Envisiontec, Inc., et al `537 Patent - Claim 81 Limitation 9 "vacuum pump" `143 Patent - Claim 35 Element 4 "support representation" `143 Patent - Claim 35 Element 5 "a removable support" a device that creates a difference in pressure

This claimed element is expressly clearly. It means a computer programmed or having instructions to produce data relating to a support for the three-dimensional object. a structure that is not part of the finished object and which provides reinforcement for the object or portions of the object and can be separated from the object

05-74891 3D Systems, Inc. v. Envisiontec, Inc., et al `431 Patent - Claim 35 Element 8 "means for receiving said support representation, and for forming said three-dimensional object out of said medium substantially layer by layer, and also for forming said support out of said material substantially layer by layer, in accordance with said object and support representations." This is a means plus function element. 1. receiving the support representation the computer described at col. 8, ll. 39-59 this includes the CAD generator; the interface; the network communications such as an ETHERNET and the interface computer joining the three-dimensional object out of the medium the fluid medium described at col. 4, ll. 56-62 and col. 10, ll. 21-22 the source of synergistic stimulation described at col. 4, ll. 48-55 this includes the fluid medium which is capable of solidification as a response to prescribed stimulation and a suitable vessel a beam of UV light or an electric beam or a spray and mask or impinging radiation other than light 3. joining the support out of the material layer by layer in accordance with the object and support representation the fluid medium described at col. 4, ll. 56-62 and col. 10, ll. 21-22
