Response to Arguments
Applicant's arguments and remarks filed (3 – 20 – 2026) have been fully considered but they are not persuasiveApplicant argues…
Savoie / Savoie as modified does not teach the newly amended features of Apparatus for blocking of lenses with a blocking station having a joining position in a first location at which the lenses are connected with a block piece to form block piece-lens pairs and the rest position is different in a second location that is physically displaced from the joining position, the block piece-lens pairs being held in said rest position for a defined waiting period for further hardening of the block material.
Applicant further argues that none of the other applied references make up for the deficiency of Savoie / Savoie as modified
This is not found to be persuasive because…
As noted, Savoie teaches having several position including a joining position, with ([0059]) teaches spectacle lens L has been pressed by means of the holding head 16 of the transport device 18 with defined positioning in three dimensions onto the block piece S, which is disposed in the blocking station 14 above the exposure device 26 and provided with the blocking material M. ([0093]) going on to state that a thermoplastic blocking material such as polycaprolactone or the like (cf. U.S. Pat. No. 5763075 A, Benjamin et al., hereinafter Benjamin) could be used, so that the exposure device (at 26 in FIG. 10) would be redundant. However, in this case it would be necessary to ensure that the feed of blocking material is designed for a thermoplastic medium, which includes appropriate heating of the metering and feed devices for the blocking material and, optionally, cooling of the blocking station. Adding, that the curing is understood to take place while the lens is in a rest position. Highlighting, evidence from (Benjamin, US 5763075 A) (Col. 19, lines 25 – 30) that transforming the blocking composition from a warm state to a cool state requires loss of thermal energy and can be carried out using a variety of cooling techniques. Cooling can take place under ambient conditions in the presence of air only. As such, the exposure to ambient conditions is understood to be a means for curing (partial curing). With Benjamin on (Col. 47, lines 55 – 59) adding that that after the application of the molten blocking material to the lens, the assembly is allowed to set for 10 to 15 seconds, allowing the resin to harden, then the blocked lens was moved and allowed to set for 1 hour prior to further processing. As such, providing for cooling / partial harden to transpire after the deposition of the blocking material, namely at the metering device 24 which is horizontally spaced from the exposure device, ([0057]). Finally, the same concept is taught by Freson in a chronologically overlapping manner by a platform with a carrousel rotation. With Freson teaching on ([0110]) teaches a blocking system as illustrated on (Fig. 3) comprises a carousel 25 comprising four machining stations A, B, C, D. As shown in (Fig. 3) the lens blocking station has at least 4 block piece seats for chronologically overlappingly / simultaneous processing. Highlighting stations, A, B, C and D also comprise a receiving position, joining, rest and removal positions. ([0098]) teaches that advantageously, after the previous providing step d), the method according to the present embodiment further comprises a cooling step e), in which the blocking material 14 cools from its first state temperature to an intermediate state temperature. ([0099]) teaches that the cooling of the blocking material may be active, for example using water cooling, or passive, for example heat exchange with ambient air. ([0103]) teaches the blocking material is then cooled to a blocking state temperature. The final state temperature being close to room temperature, for example around 21° C. ([0104]) teaches the final state temperature is chosen so that the blocking material is solid at such temperature. ([0121]) notes that the second handling device 28 may also carry out the first blocking b), the moving c), the placing f) and the second blocking g) steps of the blocking method as described previously. As such, the apparatus is adapted to move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs. Highlighting, that as the blocking material is applied in (B), its beings to cool as its being exposed to ambient conditions, i.e., passive cooling, for example heat exchange with ambient air. As such, moving from (B) to (C) is understood to provide for exposure of the move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs
This is unpersuasive because as explained above there was not found to be deficiency in Savoie / Savoie as modified

Savoie teaches the following:
([0002]) teaches that the invention particularly relates to a device for blocking spectacle lenses.
& c.) ([0043]) teaches that a blocking station 14 in which the spectacle lens L can be blocked on a block piece S by means of a temporarily deformable blocking material M, and a transport device 18, which comprises a holding head 16 for the spectacle lens L and by means of which a relative movement between the spectacle lens L held at the holding head 16 on the one hand and the measuring station 12 as well as the blocking station 14 on the other hand can be produced. ([0059]) teaches spectacle lens L has been pressed by means of the holding head 16 of the transport device 18 with defined positioning in three dimensions onto the block piece S, which is disposed in the blocking station 14 above the exposure device 26 and provided with the blocking material M. As such, the exposure device 26 provides for a first location at which the lenses are connected with a block piece to form block piece-lens pairs. ([0089]) teaches (Fig. 34) illustrates that wherein the spectacle lens L is pressed by its workpiece surface F1, which is to be blocked, into the blocking material M, which is applied to the block piece 5. As such, the exposure device 26 provides for a joining position in which the lenses are connected via pressing by means of the holding head 16 of the transport device 18 with a block piece to form block piece-lens pairs. Highlighting, while only one piece is shown being processed. The duplication of parts may be recited regarding implementing a secondary joining of block piece S and lens L in the block station. See In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960).
, e.), g.) & i.) Additionally, regarding the chronologically overlappingly aspect of the apparatus, i.e., the simultaneous processing of more than one lens. The case law for sequential vs simultaneous may be recited. Where, generally, no invention is involved in the broad concept of performing simultaneously operations which have previously been performed in sequence. In re Tatincloux, 108 USPQ 125.
([0043]) teaches a measuring station 12 for detection of the orientation and of geometry data of the spectacle lens L to be blocked. Where the measuring station 12 provides for an aligning apparatus.
([0042]) teaches that the holding head 16 for the spectacle lens L is in that case constructed to be rotatable and tiltable (tilt axes A, B, rotational axis C), with closed-loop control in rotational angle, in three dimensions. ([0081]) teaches that the spectacle lens L is centered by means of the (parallel) grippers 48 on the deposit 46, whereupon the second slide 44 moves rearwardly into measuring position above the optical measuring device 40 of the measuring station 12, where the spectacle lens L is optically measured. ([0084]) teaches that the holding head 16 (of the transport device) is moved along the linear axis X together with the spectacle lens L, which is attached by suction, over the mechanical measuring device 42 of the measuring station 12. ([0085]) adding that the holding head 16 is moved downwardly along the linear axis Z in order to bring the spectacle lens L attached by suction into contact with the mechanical measuring device 42 of the measuring station 1. Highlighting, that the measuring station 12 is understood to utilize the holding head 16 of the transport device 16 in conjunction with the data / measurements as a means for adjusting and position the lenses during production.
([0043]) teaches a transport device 18, which comprises a holding head 16 for the spectacle lens L and by means of which a relative movement between the spectacle lens L held at the holding head 16 on the one hand and the measuring station 12 as well as the blocking station 14 on the other hand can be produced. Additionally, ([0071]) teaches as can be seen particularly in (Fig. 18), the loading unit 50 comprises a loading arm 52 with a longitudinal axis 54, at which a loading head 56 together with at least one sucker 58, in the illustrated exemplifying embodiment two suckers 58 disposed diametrically opposite with respect to the longitudinal axis 54, is or are mounted to be rotatable through 180° about the longitudinal axis 54 of the loading arm 52.
([0047]) teaches that for this purpose a universal ball joint 84 is provided in the center of the lower plate 82. Two drives 86 arranged at 90° between the plates 80, 82 serve for tilting (tilt axes A and B) the upper plate 80 against the force of tension springs 88, which are tensioned between the plates 80, 82 and of which one tension spring 88 is illustrated by way of example in (Fig. 6). A further drive 90 is provided on the upper plate 80 and serves for rotating, with closed-loop control in rotational angle, a hollow shaft 92 (rotational axis C).
As shown in (Fig. 10), the blocking station is only found to have a single seat. However, the duplication of parts may be recited for providing the blocking station with a second seat for holding a second lens. Where, the court held that mere duplication of parts has no patentable significance unless a new and unexpected result is produced, see In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960)
& j.) ([0089]) teaches that the spectacle lens L is pressed by its workpiece surface F1, which is to be blocked, into the blocking material M, which is applied to the block piece 5, while leaving the blocking material receiving gap C (see for this purpose also Fig. 20). Highlighting, as shown in (Fig. 20) the block piece being located in the respective block piece seat and provided with block material. Adding, that this pressing is prior to the curing. As such, the attachment is understood to be connected in a detachable manner.
& l.) ([0089]) teaches that the exposure device 26 (cf. Fig. 10) is activated and the blocking material M is cured by means of ultraviolet light. With ([0093]) teaches that although there was explicit discussion above of a blocking material curable by light, it will be evident to the expert that in principle other blocking materials can also be used. Thus, for example, a thermoplastic blocking material such as polycaprolactone or the like (cf. U.S. Pat. No. 5763075 A, Benjamin et al., hereinafter Benjamin) could be used, so that the exposure device (at 26 in FIG. 10) would be redundant. However, in this case it would be necessary to ensure that the feed of blocking material is designed for a thermoplastic medium, which includes appropriate heating of the metering and feed devices for the blocking material and, optionally, cooling of the blocking station. Adding, that the curing is understood to take place while the lens is in a rest position.Highlighting, evidence from (Benjamin, US 5763075 A) (Col. 19, lines 25-30) that transforming the blocking composition from a warm state to a cool state requires loss of thermal energy and can be carried out using a variety of cooling techniques. Cooling can take place under ambient conditions in the presence of air only. As such, the exposure to ambient conditions is understood to be a means for curing (partial curing). Benjamin on (Col. 47, lines 55 – 59) adding that that after the application of the molten blocking material to the lens, the assembly is allowed to set for 10 to 15 seconds, allowing the resin to harden, then the blocked lens was moved and allowed to set for 1 hour prior to further processing.With Savoie noting on ([0057]) that the blocking station 14 is movable by means of the first slide 22 of the transport device 18 from the metering device 24, in which the blocking material M can be centrally or decentrally applied to the block piece S, to the exposure device 26 and vice versa. As such, transportation from the metering device 24, in ambient conditions, is understood to (partially) cure the blocking material M applied to the block piece S. While also providing two different positions a joining position with the metering device and a rest position in ambient conditions caused by movement of the transport device. Highlighting, implementing a thermoplastic blocking material as detailed by Savoie, and then transforming the blocking composition from a warm state to a cool state as detailed by Benjamin would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the processing method of Savoie by cooling the deposited transforming the blocking in ambient conditions as taught by Benjamin, due to the fact it would amount to nothing more than a use of a known cooling technique to harden and cure the thermoplastic block material, for its intended use, in a known environment, to accomplish entirely expected result, as suggested by Benjamin.
As noted above evidenced provided by Benjamin on (Col. 47, lines 55 – 59) adding that that after the application of the molten blocking material to the lens, the assembly is allowed to set for 10 to 15 seconds, allowing the resin to harden, then the blocked lens was moved and allowed to set for 1 hour prior to further processing. As such, the block piece-lens pairs being held in said rest position for a defined waiting period for further hardening of the block material.
Regarding Claim 59, Savoie is ambiguous on chronologically overlappingly connecting at least each of two lenses. In analogous art for a lens blocking apparatus, that comprises a lens blocking station, conveyor and various handling devices, Freson suggests details regarding implementing a carousel in a blocking station as a means to transport a lens and block piece seat in a chronologically overlappingly way, and in this regard, Freson teaches the following:
As illustrated in (Fig. 3) machining stations B provides for a joining position in a first location at which the lenses are connected with a block piece to form block piece-lens pairs. ([0095]) teaches that the blocking material 14 is provided at a first state temperature, the first state temperature being for example above its melting or softening temperature. As such, the material is provided at a first temperature.
, e.), g.), i.), k.) & l.) ([0110]) teaches a blocking system as illustrated on (Fig. 3) comprises a carousel 25 comprising four machining stations A, B, C, D. As shown in (Fig. 3) the lens blocking station has at least 4 block piece seats for chronologically overlappingly / simultaneous processing. Highlighting stations, A, B, C and D also comprise a receiving position, joining, rest and removal positions.
([0098]) teaches that advantageously, after the previous providing step d), the method according to the present embodiment further comprises a cooling step e), in which the blocking material 14 cools from its first state temperature to an intermediate state temperature. ([0099]) teaches that the cooling of the blocking material may be active, for example using water cooling, or passive, for example heat exchange with ambient air. ([0103]) teaches the blocking material is then cooled to a blocking state temperature. The final state temperature being close to room temperature, for example around 21° C. ([0104]) teaches the final state temperature is chosen so that the blocking material is solid at such temperature. ([0121]) notes that the second handling device 28 may also carry out the first blocking b), the moving c), the placing f) and the second blocking g) steps of the blocking method as described previously. As such, the apparatus is adapted to move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs. Highlighting, that as the blocking material is applied in (B), its beings to cool as its being exposed to ambient conditions, i.e., passive cooling, for example heat exchange with ambient air. As such, moving from (B) to (C) is understood to provide for exposure of the move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the production method and apparatus for blocking lenses that comprises a blocking station, conveyor and various handling devices, of Savoie. By modifying the blocking station to include a carousel as a means for transporting the lens and blocking seats within the blocking station, as taught by Freson. Highlighting, implementation of carousel provides a means for processing several articles at once, (Fig. 3). Furthermore, the simple substitution of one known element for another to obtain predictable results and/or the use of known technique to improve similar devices (methods, or products) in the same way allows for the recitation of KSR case law. Where, "A person of ordinary skill has good reason to pursue the known option within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense." KSR int'l Co. v. Teleflex Inc., 127 S. Ct. 1727, 82 USPQ2d 1385 (2007).

However, in this case it would be necessary to ensure that the feed of blocking material is designed for a thermoplastic medium, which includes appropriate heating of the metering and feed devices for the blocking material and, optionally, cooling of the blocking station. Highlighting, evidence from (Benjamin, US-5,763,075) (Col. 19, lines 25-30) that transforming the blocking composition from a warm state to a cool state requires loss of thermal energy and can be carried out using a variety of cooling techniques. Cooling can take place under ambient conditions in the presence of air only. As such, the exposure to ambient conditions is understood to be a means for curing (partial curing). Benjamin on (Col. 47, lines 55-59) adding that that after the application of the molten blocking material to the lens, the assembly is allowed to set for 10 to 15 seconds, allowing the resin to harden, then the blocked lens was moved and allowed to set for 1 hour prior to further processing.With Savoie noting on ([0057]) that the blocking station 14 is movable by means of the first slide 22 of the transport device 18 from the metering device 24, in which the blocking material M can be centrally or decentrally applied to the block piece S, to the exposure device 26 and vice versa. As such, transportation from the metering device 24, in ambient conditions, is understood to (partially) cure the blocking material M applied to the block piece S. While also providing two different positions a joining position with the metering device and a rest position in ambient conditions caused by movement of the transport device.
As noted above evidenced provided by Benjamin on (Col. 47, lines 55 – 59) adding that that after the application of the molten blocking material to the lens, the assembly is allowed to set for 10 to 15 seconds, allowing the resin to harden, then the blocked lens was moved and allowed to set for 1 hour prior to further processing. As such, the block piece-lens pairs being held in said rest position for a defined waiting period for further hardening of the block material.
Regarding Claim 93, Savoie is ambiguous on chronologically overlappingly connecting at least each of two lenses. In analogous art for a lens blocking apparatus, that comprises a lens blocking station, conveyor and various handling devices, Freson suggests details regarding implementing a carousel in a blocking station as a means to transport a lens and block piece seat in a chronologically overlappingly way, and in this regard, Freson teaches the following:
, c.), e.), g.), i.) & j.) ([0110]) teaches a blocking system as illustrated on FIG. 3 comprises a carousel 25 comprising four machining stations A, B, C, D. As shown in (Fig. 3) the lens blocking station has at least 4 block piece seats for chronologically overlappingly / simultaneous processing. Highlighting stations, A, B, C and D also comprise a receiving position, joining, rest and removal positions.
As illustrated in (Fig. 3) machining stations B provides for a joining position in a first location at which the lenses are connected with a block piece to form block piece-lens pairs. ([0095]) teaches that the blocking material 14 is provided at a first state temperature, the first state temperature being for example above its melting or softening temperature. As such, the material is provided at a first temperature.
([0098]) teaches that advantageously, after the previous providing step d), the method according to the present embodiment further comprises a cooling step e), in which the blocking material 14 cools from its first state temperature to an intermediate state temperature. ([0099]) teaches that the cooling of the blocking material may be active, for example using water cooling, or passive, for example heat exchange with ambient air. ([0103]) teaches the blocking material is then cooled to a blocking state temperature. The final state temperature being close to room temperature, for example around 21° C. ([0104]) teaches the final state temperature is chosen so that the blocking material is solid at such temperature. ([0121]) notes that the second handling device 28 may also carry out the first blocking b), the moving c), the placing f) and the second blocking g) steps of the blocking method as described previously. As such, the apparatus is adapted to move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs. Highlighting, that as the blocking material is applied in (B), its beings to cool as its being exposed to ambient conditions, i.e., passive cooling, for example heat exchange with ambient air. As such, moving from (B) to (C) is understood to provide for exposure of the move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the production method and apparatus for blocking lenses that comprises a blocking station, conveyor and various handling devices, of Savoie. By modifying the blocking station to include a carousel as a means for transporting the lens and blocking seats within the blocking station, as taught by Freson. Highlighting, implementation of carousel provides a means for processing several articles at once, (Fig. 3). Furthermore, the simple substitution of one known element for another to obtain predictable results and/or the use of known technique to improve similar devices (methods, or products) in the same way allows for the recitation of KSR case law. Where, "A person of ordinary skill has good reason to pursue the known option within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense." KSR int'l Co. v. Teleflex Inc., 127 S. Ct. 1727, 82 USPQ2d 1385 (2007).Regarding claim 94,

Savoie teaches the following:
([0002]) teaches that the invention particularly relates to a device for blocking spectacle lenses.
([0043]) teaches that a blocking station 14 in which the spectacle lens L can be blocked on a block piece S by means of a temporarily deformable blocking material M, and a transport device 18, which comprises a holding head 16 for the spectacle lens L and by means of which a relative movement between the spectacle lens L held at the holding head 16 on the one hand and the measuring station 12 as well as the blocking station 14 on the other hand can be produced. ([0087]) teaches that in (Fig. 32) the blocking material M is applied in a predetermined amount to the block piece S by means of the metering head 28 of the metering device 24, whereupon the metering head 28 is pivoted back. ([0089]) teaches (Fig. 34) illustrates that wherein the spectacle lens L is pressed by its workpiece surface F1, which is to be blocked, into the blocking material M, which is applied to the block piece 5. ([0059]) notes that the spectacle lens L is been pressed by means of the holding head 16 of the transport device 18.As such, a joining position in which the lenses are connected via pressing by means of the holding head 16 of the transport device 18 with a block piece to form block piece-lens pairs is understood to be disclosed. Highlighting, while only one piece is shown being processed. The duplication of parts may be recited regarding implementing a secondary joining of block piece S and lens L in the block station. See In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960).
, d.) f.) Additionally, regarding the chronologically overlappingly aspect of the apparatus, i.e., the simultaneous processing of more than one lens. The case law for sequential vs simultaneous may be recited. Where, generally, no invention is involved in the broad concept of performing simultaneously operations which have previously been performed in sequence. In re Tatincloux, 108 USPQ 125.
([0043]) teaches a measuring station 12 for detection of the orientation and of geometry data of the spectacle lens L to be blocked. Where the measuring station 12 provides for an aligning apparatus.
([0043]) teaches a transport device 18, which comprises a holding head 16 for the spectacle lens L and by means of which a relative movement between the spectacle lens L held at the holding head 16 on the one hand and the measuring station 12 as well as the blocking station 14 on the other hand can be produced. Additionally, ([0071]) teaches as can be seen particularly in FIG. 18, the loading unit 50 comprises a loading arm 52 with a longitudinal axis 54, at which a loading head 56 together with at least one sucker 58, in the illustrated exemplifying embodiment two suckers 58 disposed diametrically opposite with respect to the longitudinal axis 54, is or are mounted to be rotatable through 180° about the longitudinal axis 54 of the loading arm 52.
([0047]) teaches that for this purpose a universal ball joint 84 is provided in the center of the lower plate 82. Two drives 86 arranged at 90° between the plates 80, 82 serve for tilting (tilt axes A and B) the upper plate 80 against the force of tension springs 88, which are tensioned between the plates 80, 82 and of which one tension spring 88 is illustrated by way of example in FIG. 6. A further drive 90 is provided on the upper plate 80 and serves for rotating, with closed-loop control in rotational angle, a hollow shaft 92 (rotational axis C).
As shown in (Fig. 10), the blocking station is only found to have a single seat. However, the duplication of parts may be recited for providing the blocking station with a second seat for holding a second lens. Where, the court held that mere duplication of parts has no patentable significance unless a new and unexpected result is produced, see In re Harza, 274 F.2d 669, 124 USPQ 378 (CCPA 1960)
Regarding Claim 94, Savoie is ambiguous on chronologically overlappingly connecting at least each of two lenses. In analogous art for a lens blocking apparatus, that comprises a lens blocking station, conveyor and various handling devices, Freson suggests details regarding implementing a carousel in a blocking station as a means to transport a lens and block piece seat in a chronologically overlappingly way, and in this regard, Freson teaches the following:
, d.), f.), h.), i.), j.), k.) & l.) ([0110]) teaches a blocking system as illustrated on FIG. 3 comprises a carousel 25 comprising four machining stations A, B, C, D. As shown in (Fig. 3) the lens blocking station has at least 4 block piece seats for chronologically overlappingly / simultaneous processing. Highlighting stations, A, B, C and D also comprise a receiving position, joining, rest and removal positions.
As detailed in (Fig. 3) the machining stations A provides for a receiving position.
As illustrated in (Fig. 3) machining stations B provides for a joining position in a first location at which the lenses are connected with a block piece to form block piece-lens pairs. ([0095]) teaches that the blocking material 14 is provided at a first state temperature, the first state temperature being for example above its melting or softening temperature. As such, the material is provided at a first temperature.
([0098]) teaches that advantageously, after the previous providing step d), the method according to the present embodiment further comprises a cooling step e), in which the blocking material 14 cools from its first state temperature to an intermediate state temperature. ([0099]) teaches that the cooling of the blocking material may be active, for example using water cooling, or passive, for example heat exchange with ambient air. ([0103]) teaches the blocking material is then cooled to a blocking state temperature. The final state temperature being close to room temperature, for example around 21° C. ([0104]) teaches the final state temperature is chosen so that the blocking material is solid at such temperature. ([0121]) notes that the second handling device 28 may also carry out the first blocking b), the moving c), the placing f) and the second blocking g) steps of the blocking method as described previously. As such, the apparatus is adapted to move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs. Highlighting, that as the blocking material is applied in (B), its beings to cool as its being exposed to ambient conditions, i.e., passive cooling, for example heat exchange with ambient air. As such, moving from (B) to (C) is understood to provide for exposure of the move the block piece seats from the joining position (B) into a rest position after partial hardening (C) of the block material of the block piece- lens pairs.
As detailed in (Fig. 3), the machining stations D provides for a removal position.

It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the production method and apparatus for blocking lenses that comprises a blocking station, conveyor and various handling devices, of Savoie. By modifying the blocking station to include a carousel as a means for transporting the lens and blocking seats within the blocking station, as taught by Freson. Highlighting, implementation of carousel provides a means for processing several articles at once, (Fig. 3). Furthermore, the simple substitution of one known element for another to obtain predictable results and/or the use of known technique to improve similar devices (methods, or products) in the same way allows for the recitation of KSR case law. Where, "A person of ordinary skill has good reason to pursue the known option within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense." KSR int'l Co. v. Teleflex Inc., 127 S. Ct. 1727, 82 USPQ2d 1385 (2007).B.) Claim(s) 84, is/are rejected under 35 U.S.C. 103 as being unpatentable over Savoie in view of Freson and in further view of Cormier et al. (US-2017/0,239,774, hereinafter Cormier)
Regarding claim 84,
Further comprising at least one block piece seat for a block piece, wherein a major axis of the block piece seat is inclined with respect to vertical.
Savoie teaches the following:
([0068]) teaches a second clamping ring 76, which is arranged below the first clamping ring 72 and rotatable with respect to the first clamping ring 72. ([0068]) adding that the second clamping ring having radially extending clamping projections 78 by way of which the clamping projections V of the block piece S bearing against the clamping jaws 74 of the first clamping ring 72 in the received state of the block piece S can be clamped. Formed at the clamping projections 78 of the second clamping ring 76 (and, as an introduction aid, optionally also at the clamping jaws 74 of the first clamping ring 72) are inclined surfaces 138 by way of which rotation of the second clamping ring 76 relative to the first clamping ring 72 is produced when the block piece S is pressed into the blocking station 14.
Regarding Claim 84, Savoie as modified by Freson utilized the duplication of parts concerning the blocking station having at least two block piece seats. As such, Savoie is vague on the blocking station has at least two block piece seats. In analogous art for a lens blocking apparatus that comprises a block station, and a block piece seat, Cormier suggests details regarding optimizing the block piece seat’s position via inclining and in this regard, Cormier teaches the following:
([0054]) teaches workpiece support 12 at the prism ring 44 of FIG. 15 is not chamfered with respect to the blocker axis V (prism angle of 0°, the workpiece support 12′ at the prism ring 44′ according to FIG. 17 is chamfered or inclined with respect to the blocker axis V (here by a prism angle of 5°). A plurality of differently chamfered prism rings 44, 44′, which are, for example, stepped by degrees (0°, 1°, 2°, 3°, etc.) can be stocked here so as to cover the desired range of prism angles for blocking. As such, an inclined block piece seat is understood to be a binary option where the block piece seat is either inclined or not. Furthermore, an inclined block piece seat is understood to impact the desired range of prism angles that are blocked
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the production method and apparatus for blocking lenses that comprises a blocking station, conveyor and various handling devices, of Savoie as modified. By augmenting the block piece seat to have an incline, as taught by Cormier. Highlighting, implementing an inclined block piece seat provides a means for tailoring the desired range of prism angles that are blocked, ([0054]). Accordingly, the case law for result effective variable may be recited regarding implementing an inclined block piece seat. Where, it is well settled that determination of optimum values of cause effective variables such as these process parameters is within the skill of one practicing in the art. In re Boesch, 205 USPQ 215 (CCPA 1980). Furthermore, choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success, i.e., an inclined block piece seat or not inclined block piece seat and/or the simple substitution of one known element for another to obtain predictable results allows for the recitation of KSR case law. Where, "A person of ordinary skill has good reason to pursue the known option within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense." KSR int'l Co. v. Teleflex Inc., 127 S. Ct. 1727, 82 USPQ2d 1385 (2007).
