Taking into account the complexities involved in this case, on account of a hiatus created by reason of the law not being brought into force in time, we are of the view that the first appeals, filed by respondent no.3 in the High Court being FAO No.292/06 and FAO No.293/06, would remain in the High Court. The said appeals would be heard and disposed of by the High Court in accordance with law under Section 116 of the said 1970 Act as it stood on 19.10.06. The High Court will hear and decide the validity of the Order passed by the Controller dated 23.8.06 rejecting “pre-grant opposition” filed by respondent no.3. We are informed that there are hardly one or two matters of this nature which are pending. Therefore, we are of the view that respondent no.3 cannot be let without remedy. In the special circumstances of this case, particularly when after 2.4.07 appeals against orders rejecting “pre-grant opposition” are not maintainable and particularly when FAO No.292/06 and FAO No.293/06 were filed by respondent no.3 prior to 2.4.07 under the old law, we are of the view that these two appeals shall be heard and decided by the High Court in accordance with law. The Appellate Board 27after 2.4.07 is entitled to hear appeals only arising from orders passed by the Controller under Section 25(4), i.e., in cases of orders passed in “post-grant opposition”. Therefore, there is no point in transferring the pending FAO No.292/06 and FAO No.293/06 to the Appellate Board which has no authority to decide matters concerning “pre-grant opposition”. Moreover, it may be noted that even Section 117G, which refers to transfer of pending proceedings to the Appellate Board, is also brought into force vide Notification dated 3.4.07. Keeping in mind the peculiar nature of the problem in hand, we are of theview that ends of justice would be subserved if the High Court is directed to hear and decide the appeals bearing FAO No.292/06 and FAO No.293/06 in accordance with law as it then stood, i.e., under Section 116 under Patents (Amendment) Act, 1999 against Orders passed by the Controller in “pre-grant opposition” proceedings.
