A&J International Patent Office offers free one-on-one online consultations. We advise broadly — from patent, utility-model, design and trademark filings in Japan to prior-art searches, customs provisional dispositions and plant-variety registration. Consultations are available in Korean, and important correspondence is also provided in Korean. Inquiries are accepted 24/7, with replies during weekday business hours.
Information received during consultations is never disclosed to third parties. Only the client and A&J’s consultant can view the content, so you can inquire with confidence.
