PCT申请处于国际阶段，国家知识产权局为受理局，刚收到国际检索报告，申请人现在想撤回优先权要求，不知该如何办理？
是向受理局提，还是必须向国际局提？
是否有撤回优先权声明的表格，如果有，在哪里可以下载？
另外，有何注意事项？
期待各位大侠指点。谢先！
you can withdraw p claim
do this at IB or RO
the form is Form PCT/IB/372
http://www.wipo.int/export/sites/www/pct/en/forms/ib/editable/ed_ib372.pdf
must do it before the expiration of 30 months from the priority date.
free of charge.
signed by all the applicants. (or agent)
if the notice of withdrawal reaches the International Bureau after the completion of the technical preparations for international publication, the International Bureau may proceed with the international publication on the basis of the time limit for international publication as computed from the original priority date.
generally, it is risky to withdraw a p claim, you must ensure there is no intervening application
