Abstract
The present invention discloses a data file writing method and system, and a data file reading method and system. The data file writing method is used for writing to-be-written data to a data file, and comprises: obtaining one or more piece of to-be-written data; setting a first character string; taking each piece of to-be-written data as a unit and adding the first character string in each unit, and locating the first character string at the front end of each unit for identifying each unit; and writing each unit to the data file. By the present invention, even if it occurs in the data file that a part of data is damaged, undamaged data in the data file can still be searched for to be read.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
