THE REPLY FILED 12 April 201 2 FAILS TO PLACE THIS APPLICATION IN CONDITION FOR ALLOWANCE. 
NO NOTICE OF APPEAL FILED 

1 . S The reply was filed after a final rejection. No Notice of Appeal has been filed. To avoid abandonment of this application, applicant must timely file 

one of the following replies: (1) an amendment, affidavit, or other evidence, which places the application in condition for allowance; 
(2) a Notice of Appeal (with appeal fee) in compliance with 37 CFR 41 .31 ; or (3) a Request for Continued Examination (RCE) in compliance with 
37 CFR 1.114 if this is a utility or plant application. Note that RCEs are not permitted in design applications. The reply must be filed within one of 
the following time periods: 

a) □ The period for reply expires months from the mailing date of the final rejection. 

b) K| The period for reply expires on: (1) the mailing date of this Advisory Action; or (2) the date set forth in the final rejection, whichever is later. 
In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of the final rejection. 
A prior Advisory Action was mailed more than 3 months after the mailing date of the final rejection in response to a first after-final reply filed 

within 2 months of the mailing date of the final rejection. The current period for reply expires months from the mailing date of 

the prior Advisory Action or SIX MONTHS from the mailing date of the final rejection, whichever is earlier. 

Examiner Note: If box 1 is checked, check either box (a), (b) or (c). ONLY CHECK BOX (b) WHEN THIS ADVISORY ACTION IS THE 
FIRST RESPONSE TO APPLICANTS FIRST AFTER-FINAL REPLY WHICH WAS FILED WITHIN TWO MONTHS OF THE FINAL 
REJECTION. ONLY CHECK BOX (c) IN THE LIMITED SITUATION SET FORTH UNDER BOX (c). See MPEP 706.07(f). 
Extensions of time may be obtained under 37 CFR 1 .136(a). The date on which the petition under 37 CFR 1.136(a) and the appropriate 
extension fee have been filed is the date for purposes of determining the period of extension and the corresponding amount of the fee. The 
appropriate extension fee under 37 CFR 1 .1 7(a) is calculated from: (1 ) the expiration date of the shortened statutory period for reply originally 
set in the final Office action; or (2) as set forth in (b) or (c) above, if checked. Any reply received by the Office later than three months after the 
mailing date of the final rejection, even if timely filed, may reduce any earned patent term adjustment. See 37 CFR 1 .704(b). 
NOTICE OF APPEAL 

2. □ The Notice of Appeal was filed on . A brief in compliance with 37 CFR 41 .37 must be filed within two months of the date of filing the 

Notice of Appeal (37 CFR 41 .37(a)), or any extension thereof (37 CFR 41 .37(e)), to avoid dismissal of the appeal. Since a Notice of 
Appeal has been filed, any reply must be filed within the time period set forth in 37 CFR 41 .37(a). 
AMENDMENTS 



3. £4 The proposed amendments filed after a final rejection, but prior to the date of filing a brief, will not be entered because 

a) £3 They raise new issues that would require further consideration and/or search (see NOTE below); 

b) n They raise the issue of new matter (see NOTE below); 

c) They are not deemed to place the application in better form for appeal by materially reducing or simplifying the issues for 
appeal; and/or 

d) ^ They present additional claims without canceling a corresponding number of finally rejected claims. 
^ NOTE: See Continuation Sheet . (See 37 CFR 1 .1 1 6 and 41 .33(a)). 

4. n The amendments are not in compliance with 37 CFR 1 .121 . See attached Notice of Non-Compliant Amendment (PTOL-324). 

5. n Applicant's reply has overcome the following rejection(s): . 

6. n Newly proposed or amended claim(s) would be allowable if submitted in a separate, timely filed amendment canceling the non- 

allowable claim(s). 

7. ^ For purposes of appeal, the proposed amendment(s): (a) ^ will not be entered, or (b) □ will be entered, and an explanation of how the 

new or amended claims would be rejected is provided below or appended. 
AFFIDAVIT OR OTHER EVIDENCE

Advisory Action Before the Filing of an Appeal Brief 



Part of Paper No. 20120419 



Continuation Sheet (PTOL-303) 



Application No. 10/595,145 



Continuation of 3. NOTE: Applicant has added new claims 10-13, which recite new limitations. These claims would require further search 
and consideration. 



Continuation of 11 . does NOT place the application in condition for allowance because: Regarding the outstanding objection to the 
Specification that the claim limitation "extra port is unique to a particular new session" lacks proper antecedent basis and support in the 
Specification, Applicant cites Fig. 3 as well as the accompanying text on page 7, lines 1 1 -28 as providing the necessary support. However, 
the examiner would respectfully disagree that these cited portions would provide the required support. To be sure, the cited portions do 
disclose that "[i]n the example in figure 3, five media session flows are transported in the MHN" and that "a media session between PI1 and 
POI for example is the cause of an extra port XP1 ", among other teachings and disclosures. The cited portions appear to teach only that 
there are five "first ports P1 1-5" and five "second ports POI-5" and that these ports are coupled to each other by what would appear to be 
connections, as shown in Figure 3, not sessions. These connections also visually appear to connect to every one of the five "extra ports 
XP1-5", thus also visually disclosing that all of the "first ports PI1-5", "second ports POI-5" and "extra ports XP1-5" are interconnected to 
each other. These would appear to be connections though, not necessarily sessions. Regarding sessions, there is the teaching that "a 
media session between PI1 and POI for example is the cause of an extra port XP1". There is no teaching that would be obvious to an 
ordinary artisan that the each of the "five media sessions flows" taught in Fig. 3 are separately connected by separate pairs of ports, as the 
Applicant seems to imply, and that each of these sessions connected by supposedly separate pairs of ports has its own, unique "extra 
port". Furthermore, in the same passage, Applicant discloses that "media multiparty sessions between more than two ports in the MHN are 
treated in a similar manner. If a session is set up between one first port PI1 and a number of second ports, POI-n, an extra port [XP1] is 
always assigned to this sessions". This teaching regarding "media multiparty sessions" would seem to complicate the scenario in fig. 3; for 
example, if such "multiparty session" were assigned PI1 and "a number of second ports", POI -5, then there would clearly not be a simple, 
straightforward one-to-one unique correspondence between "first ports" and "second ports" as Applicant seems to suggest. This leaves 
open then the possibility that ports are dynamically assigned to sessions, and under such circumstances, it is not at all obvious the cited 
portions would teach to an ordinary artisan that "extra port is unique to a particular new session". 

Applicant further argues that the reference Mazzola does not disclose the same limitation at issue above. Applicant argues that in 
Mazzola, "Mazzola's network switch can utilize the same one or more ports to forward frames associated with another session from 
another sending network entity to the same receiving network entities. Stated another way, Mazzola's network switch can utilize the same 
port to send frames to a particular receiving network entity even when the frames are part of multiple sessions and are sent by multiple 
sending network entities. Hence, Mazzola does not disclose where the port or ports are unique (i.e., limited) to a particular session but 
instead discloses where the port is based on the destination address of the receiving network entity and the same receiving network entity 
can have multiple sessions using the same port with multiple sending network entities", (page 10 of Response) However, the examiner 
would like to note here that the limitation at issue, "extra port is unique to a particular new session" may also be interpreted as meaning that 
each particular new session has only one, fixed "extra port" (either hardware or software port(s)) assigned to it; that is, a particular new 
session is not associated with a first "extra port" now and then subsequently associated with another, different "extra port". This is the 
scenario taught in Mazzola because the "extra port" taught in Mazzola is associated with a particular session based on its destination and 
this association of the port with a session/destination is not changed in Mazzola, thus teaching an embodiment of this limitation. 

Applicant further argues that the references are not combinable because "the Examiner's suggested combination of [the cited references] 
would also require a substantial reconstruction and redesign of the elements shown in the primary reference Albers as well as a change in 
the basic principle under which Albers's system was designed to operate" (page 1 1 of Response). In response to this argument, please 
note that the test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the 
primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is 
what the combined teachings of the references would have suggested to those of ordinary skill in the art. See In re Keller, 642 F.2d 413, 
208 USPQ 871 (CCPA 1981). Therefore, with all due respect, this argument is not persuasive. 

In response to applicant's argument that the examiner's conclusion of obviousness is based upon improper hindsight reasoning, it must be 
recognized that any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning. But so long as it 
takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made, and does not 
include knowledge gleaned only from the applicant's disclosure, such a reconstruction is proper. See In re McLaughlin, 443 F.2d 1392, 
170 USPQ 209 (CCPA 1971). In this case, proper motivation to combine was provided in the rejections and thus the examiner respectfully 
does not find Applicant's arguments against the combinability of the references persuasive..
