DPS will strive to ensure that the documents and publications we provide are up to date, accurate and in good condition. Most of the information that DPS sells is derived from large inventories purchased from the U.S. government and DPS uses it's proprietary software to further improve the quality of portions of these documents, but DPS will not knowingly change the contents of these documents and publications because we understand the legal implications of doing so. Because of the sheer volume of data, and the fact that many of the documents we receive from the U.S. government and other government sources are defective upon receipt, DPS will not be held responsible for the accuracy of the contents of the documents or publications. For instance, if there was a misspelling in an original patent document we received from the U.S. government, that misspelling will remain exactly as it was found when we received it (e.g., made by a patent applicant, the patent examiner, publications author, etc.). We may, however, add the corrected word to an electronic index so it can be found in search systems, but we can't be sure we've found all misspellings in such cases. We have reported, and will continue to report problems we find with documents and publications to the proper authorities, but we must pass them on to the ACCOUNT HOLDER exactly as they come from the source provider. To do otherwise means that we would be changing a legal document that we do not have the authority to change. We ask that you report problems to us, and we will pass them on to the proper authority as necessary and confirm this to you, if you desire. If you receive a defective document and the original document we receive is also defective, we will attempt to resolve this by acquiring a new copy of the document at no additional charge to you. We ask that you notify us of the defective document, and it will be your choice whether you want a credit or a replacement document.
