Office Action

§DP
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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The 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. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp.

Further regarding Claim 11 of the present application, It is clear that all the elements of Claim 11 are to be found in patent ‘731 Claim 11. The difference between Claim 11 of the application and Claim 11 of the patent lies in the fact that the patent claim includes more elements and is thus much more specific. The elements of Claim 11 of the patent that are not included in the present application include: - a tall sidewall of the plurality of sidewalls forming a barrier between a user and the interior of the waste receptacle. Thus, the invention of Claim 11 of the patent is in effect a “species” of the “generic” invention of Claim 11 of the present application. It has been held that the generic invention is “anticipated” by the “species”. See In re Goodman, 29 USPQ2d 2010 (Fed Cir 1993). Since Claim 11 of the present application is anticipated by Claim 11 of patent ‘731, it is not patentably distinct from Claim 11 of patent ‘731.

Further regarding Claim 17 of the present application, It is clear that all the elements of Claim 17 are to be found in patent ‘731 Claim 18. The difference between Claim 17 of the application and Claim 18 of the patent lies in the fact that the patent claim includes more elements and is thus much more specific. The elements of Claim 18 of the patent that are not included in the present application include: - a tall sidewall of the plurality of sidewalls forming a barrier between a user and the interior of the waste receptacle. Thus, the invention of Claim 18 of the patent is in effect a “species” of the “generic” invention of Claim 17 of the present application. It has been held that the generic invention is “anticipated” by the “species”. See In re Goodman, 29 USPQ2d 2010 (Fed Cir 1993). Since Claim 17 of the present application is anticipated by Claim 18 of patent ‘731, it is not patentably distinct from Claim 18 of patent ‘731. Regarding Claim 18, in the present Application, Claim 18 recites “The method of servicing a lavatory of an aircraft of claim 17, wherein the plurality of sidewalls includes a tall sidewall that forms a barrier between a user and the interior of the waste receptacle.” See Claim 18 of the patent. Regarding Claim 19, in the present Application, Claim 19 recites “The method of servicing a lavatory of an aircraft of claim 17, the method further comprising: releasably fastening at least one tank to a bottom of the waste disposal apparatus, the at least one tank configured to expand a storage capability of the waste disposal apparatus, the at least one tank including a threaded insert configured to facilitate fastening of the at least one tank to the waste disposal apparatus and further configured to facilitate fastening of one or more additional tanks to the at least one tank.” See Claim 19 of the patent. Examiner notes that the present application has two references to “the at least one tank”, whereas the patent states “the tank”. However, Examiner determines that the scope of the two claims are identical and patentably indistinct. Regarding Claim 20, in the present Application, Claim 20 recites “The method of servicing a lavatory of an aircraft of claim 17, the method further comprising: mounting the waste disposal apparatus to a stand, the stand bearing a weight of the waste disposal apparatus and configured to facilitate the use of the waste disposal apparatus with the aircraft; and operatively connecting the stand to a service cart/truck to enhance a mobility and operability of the waste disposal apparatus.” See Claim 20 of the patent.
