When Paul says his righteousness in the law was blameless, he means
he closely followed the regulations of the law; or
his character was right before God.
Paul says that before his conversion to Christianity, his righteousness in the law was blameless. What does Paul mean by this?
To understand what Paul means it is important to notice that Paul says his righteousness in the law
was blameless. In other words, he is saying not that his righteousness before God was blameless, but that his righteousness in the law was blameless. Thus, if one were to make a list of each regulation of the law, one would notice that Paul followed that list blamelessly. Of course, Paul was a Pharisee, so he is referring to the Pharisaic laws that included an assortment of outward rules and regulations that had nothing to do with loving God. Thus, he is saying that when it came to following the Jewish customs, he was blameless, which he now counts as nothing compared to knowing Christ.
Some contend that when Paul says his righteousness in the law was blameless, he means that his character was acceptable to God. These contend that to be righteous is to be in the right with God. Still, even though Paul was in the right with God, he was still a sinner, so blamelessness is not perfection. Rather, blamelessness is having a character that is acceptable to God. Putting it all together, Paul is saying that he was in the right with God in that he had an acceptable character.
Interpretation 1:
Paul means that he closely followed the regulations of the law.
Summary:
Paul wants the Philippians to understand the difference between righteousness by faith and righteousness by the law. Paul was righteous by the law in the sense that he adhered to its regulations closely, yet he remained a sinner who was guilty before the judgment seat of God. That is why he will say he counts righteousness by the law as a loss compared to the surpassing worth of knowing Christ.

Minor differences:
Our authors agree that when Paul refers to being blameless when it comes to righteousness in the law, he refers not to his own sinlessness but to the fact that he consciously adhered to the Jewish laws and customs.
There is a subtle difference between some of our authors when it comes to what Paul means by the law. For Gordon Fee, when Paul refers to the law in this context, he likely refers to matters of food and drink and to the observance of days.1 In other words, Paul followed the dietary and cleanliness regulations, along with recognizing the traditional Jewish holy days.
For Frank Thielman, Paul has in mind not only food and drink and observance of days but the entire Mosaic law as it functioned in Israelite society. This means that Paul not only adhered to food laws and observed holy days but made appropriate sacrifices for the atonement of his sins.2

Interpretation 2:
Paul believed his character was right before God.
Summary:
When Paul says he was blameless according to the law, he means that he had a character that was generally acceptable to God.
