OFFICE ACTION:
DETAILED ACTION
Notice of Pre-AIA  or AIA  Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA  as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used.

Claims 2 is rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of U.S. Patent No. 12,004,884 B2 in view of Barnes et al. (US 20160081710 A1)
Regarding claim 2, ‘884 discloses: A method for cutting a transverse carpal ligament in a patient (Col. 12 lines 51-52), the method comprising: advancing a distal end of a shaft of a soft tissue cutting device into a carpal tunnel in the patient (Col. 12 lines 53-54); depressing a balloon activation lever on a handle of the soft tissue cutting device, to activate a bellows in the handle and thus inflate two balloons (Col. 12 lines 57-59 discloses depressing a balloon activation lever on a handle of the soft tissue cutting device to activate a bellows in the handle and inflate “at least one balloon”); deploying a blade along the shaft (Col. 12 lines 65-66), between the two balloons, to cut the transverse carpal ligament (Col. 12 lines 65-66); deflating the two balloons (Col. 13 lines 1-3); and removing the shaft of the soft tissue cutting device from the patient (Col. 13 line 4).
‘884 doesn’t directly disclose:
the two balloons are on either side of the shaft;
the shaft extends from the handle;
the blade is deployed from the shaft between the two balloons;
moving the blade back inside the shaft.
Barnes discloses a similar device for cutting a transverse carpal ligament in a patient (para. [0050]), including a shaft 20 of a soft tissue cutting device 10 and two balloons that extend on either side of the shaft (para. [0089]); the shaft extends from a handle 16 (Fig. 1); the blade 26 is deployed from the shaft between the two balloons (para. [0086]; Fig. 5); moving the blade back inside the shaft (i.e., after the procedure; para. [0099]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify ‘884 with Barnes such that ‘884 has two balloons on either side of the shaft and the blade is deployed from inside the shaft for purposes of positioning the device within the carpal tunnel region and to extend the “safe zone” such that any tendons or nerves are moved away from the device such that only the transverse carpal ligament is cut and not nearby at-risk structures (para. [0090]).
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA  35 U.S.C. 102 and 103 (or as subject to pre-AIA  35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA  to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 2, 4-10 are rejected under 35 U.S.C. 103 as being unpatentable over Barnes et al. (US 20160081710 A1) in view of Voellmicke et al. (US 2004/0034276 A1).
Regarding claim 2, Barnes discloses a method for cutting a transverse carpal ligament in a patient (para. [0050]), the method comprising: advancing a distal end of a shaft 20 of a soft tissue cutting device 10 into a carpal tunnel in the patient (para. [0082], [0096]); depressing a balloon activation lever 18 on a handle 16 of the soft tissue cutting device (Fig. 1), inflate two balloons (i.e., 34a, 34b) on either side of the shaft (para. [0089]), the shaft extending from the handle (Fig. 1); deploying a blade 26 out of the shaft (para. [0086]), between the two balloons (Fig. 5), to cut the transverse carpal ligament (para. [0086]); moving the blade back inside the shaft (para. [0099]); deflating the two balloons (para. [0101]); and removing the shaft of the soft tissue cutting device from the patient (para. [0101]).
Barnes also discloses an inflation device that can be any desired device including a syringe to inflate (para. [0148]).
Barnes doesn’t directly disclose a bellows in the handle that is activated to allow fluid to flow through.
In the same field of endeavor, namely devices for controlling fluid flow through a medium, Voellmicke discloses the interchangeability of syringes and bellows such that instead of using syringes to force fluid through the system, an expandable bellows 502 is provided (para. [0063]; Figs. 7A-7C).
It would have been obvious to one of ordinary skill in the art before the effective filing date to modify the device of Barnes to have a bellows in the handle that may be actuated to allow fluid to flow through for purposes of controlling the inflation and deflation of the balloons from the handle assembly by controlling the fluid flow (paras. [0063], [0065]).
Regarding claim 4, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses deploying the blade and moving the blade comprises sliding a slider 270 along the handle of the soft tissue cutting device (para. [0140]), wherein the slider is coupled with the blade (para. [0140]).
Regarding claim 5, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses verifying placement of the distal end of the shaft of the soft tissue cutting device with respect to one or more anatomical structures before inflating the two balloons (para. [0098]).
Regarding claim 6, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses the two balloons expand radially outwardly from the shaft and are located on a distal portion of the shaft, at or near a working end of the blade (paras. [0066], [0068]).
Regarding claim 7, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses deploying the blade out of the shaft comprises moving a slider button coupled with a proximal end of the blade (para. [0140]) along the handle to cause the blade to slide along a blade guideway 28 within the shaft (paras. [0082], [0087], [0088]) and thus cause a blade working end to protrude out of a slot on the shaft (para. [0087], [0088]; the active position).
Regarding claim 8, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses depressing the balloon activation lever on the handle unlocks the blade to enable it to be deployed (para. [0170] discloses a safety mechanism that prevents the blades from contacting tissue based on the balloons to prevent unwanted cutting; see also paras. [0096]-[0097]).
Regarding claim 9, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses comprising locking the balloon activation lever in a locked position via a spring-biased button (para. [0164] discloses a compression mechanism 332 with a spring 372 (see also para. [0158]); para. [0153] discloses various actuators including a push button and para. [0170] discloses any mechanism of activation disclosed which would include the push button) on the balloon activation lever, to lock the two balloons in an inflated state (para. [0170]; para. [0077] also discloses a mechanism that activates the balloons and Fig. 1 shows a push mechanism).
Regarding claim 10, Barnes and Voellmicke disclose the soft tissue cutting method of claim 9. Barnes also discloses comprising releasing the spring-biased button before deflating the two balloons (para. [0170]).
Claim 3 is rejected under 35 U.S.C. 103 as being unpatentable over Barnes and Voellmicke as applied to claim 2 and further in view of Anderson et al (US 2007/0213616 A1).
Regarding claim 3, Barnes and Voellmicke disclose the soft tissue cutting method of claim 2. Barnes also discloses filling each of the balloons with gas or fluid through a conduit to inflate the balloons and deflating the balloons by removing the gas or fluid (para. [0092]-[0095]). Barnes also discloses that inflating and deflating the balloons is accomplished by utilizing a control mechanism on the handle (para. [0077]). Barnes doesn’t directly disclose: before advancing the distal end of the shaft, priming the soft tissue cutting device by filling, via a fill port on the handle the two balloons with a gas or a fluid; and allowing the balloon activation lever to move to an extended position to cause the gas or the fluid to move from the two balloons into the bellows.
In the same field of endeavor, namely systems and methods for arteriotomy localization, Anderson discloses before advancing the distal end of the shaft, priming the soft tissue cutting device (para. [0107]).
The combination of Barnes and Voellmicke with Anderson would disclose before advancing the distal end of the shaft, priming the soft tissue cutting device by filling, via a fill port on the handle the two balloons with a gas or a fluid; and allowing the balloon activation lever to move to an extended position to cause the gas or the fluid to move from the two balloons into the bellows.
Therefore, 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 device of Barnes to have the priming step as disclosed by Anderson for purposes of preparing the device to be used in the body (para. [0107]).
