responsibility of the patent attorney?

The short answer is no - you, the inventor, are responsible for accuracy and completeness. In fact, I personally operate under the CAT principle - complete, accurate, and thorough - so when I prepare a patent application, I strive for completeness, accuracy, and thoroughness but when I send the application to the inventor(s) for approval, I emphasize to them that they must ensure that I have in fact described everything completely, accurately, and thoroughly. Once the application is prepare and approved, the attorney will file it and then the attorney has the responsibility to manage it properly - to notify the inventors of any notices from the Patent Office, to timely respond to such notices, all the way to the end when the patent is actually issued.
